Welcome to a "Geovisual Analytics Educational Web site"
Nu också på Svenska! Swedish Web site: http://ncva.itn.liu.se/?l=sv
National Center for Visual Analytics (NCVA) is a Swedish national educational and research resource for Geovisual Analytics established in 2007 with financial support from the Swedish Knowledge Foundation's Visualization Program, VINNOVA (Swedish government agency), Vetenskapsrådet (Swedish Research Council), Unilever Research, Statistics Sweden, OECD, European Commission, Eurostat, SMHI, Norrköping Kommun and others. Professor Mikael Jern is the director.
Our research focuses on geovisual analytics methods and applications for spatio-temporal data which demonstrate the usefulness of these techniques, storytelling, geographic and information visualization, spatial cognition, quantitative data analysis e.g., (geo-)statistics/data science. We are particular interested in how these techniques can support knowledge construction and insight from large statistical data demonstrated in:
Statistics eXplorer http://ncva.itn.liu.se/explorer available for education and research
Statistics eXplorer integrates common InfoVis and GeoVis methods to make sense of statistical data, uncover patterns of interests, gain insight, tell-a-story and finally communicate knowledge. eXplorer is developed based on a component architecture and includes a wide range of visualization techniques integrated in multiple linked views, map, bubble plot, bar chart, parallel coordinates Plot, Distribution Plot and many more, with sophisticated interaction techniques and interactive features supporting data exploration and analysis. eXplorer also supports integrated storytelling with a snapshot mechanism for capturing discoveries made during the exploratory data analysis process which can be used for sharing gained knowledge. Here you can find examples of interactive "Vislets" produced with eXplorer: http://ncvademo-mobile.blogspot.se/ using HTML5 also supported by your mobile device.

Geovisual Analytics and Knowledge Visualization - Concept, Idea and Implementation
The large and ever-increasing amounts of multidimensional, multi-source, time-varying digital information represent a major challenge. The need to analyze and make decisions based on these information streams, often in time-critical situations, demands integrated, automatic and sophisticated interactive tools that aid the user to manage, process visualize and interact with large information spaces. This approach has been encapsulated in the idea of Geovisual Analytics - "defined as the science of analytical reasoning facilitated by interactive visual interfaces, creative visualization and storytelling". NCVA provides interactive geovisual analytics tools:
- Analytical reasoning facilitated by interactive visual interfaces – e.g. dynamic time-linked views;
- Exploring and analyzing large spatial-temporal and multidimensional data;
- Discern trends or patterns - derive insight and Communicate discovery and knowledge effectively through Storytelling;
- NCVA is moving Geovisual Analytics Research into Practice through tools like Statistics eXplorer and Publisher;
Knowledge visualization is regarded as an independent scientific discipline and the relevance of applying storytelling towards its scientific goals is still relatively unexplored. Therefore, the emerging popularity of visual storytelling presents several interesting challenges. Our overall objective is to promote within education and research Geovisual Analytics in particular but also its relation to knowledge visualization. To this end we must make sure that education is not left behind in this rapid evolution and can keep up with the international development. In various applied research projects, geovisual analytics techniques have been developed and used to build prototype visualization applications (eg. Statistics eXplorer) that can be used to educate academia with demonstration and educational tools.
"Our mission is to use knowledge visualization to educate researchers and students in geovisual analytics and storytelling, discuss problems and possible approaches to solving them, and define appropriate directions for further research"
"Enable you to easily create and share interactive statistics news through our eXplorer Publishing tools"

Interactive Statistical Visualization with integrated Storytelling
Introducing New 2016 version of Statistics eXplorer V4.6
Statistics eXplorer V6.4 versions now available at these new locations:
World eXplorer: https://mitweb.itn.liu.se/geovis/eXplorer/world/ (countries)
Sweden eXplorer: https://mitweb.itn.liu.se/geovis/eXplorer/swe/#story=0 (counties and municipalities)
Europe eXplorer: https://mitweb.itn.liu.se/geovis/eXplorer/euro (countries, NUTS2 and NUTS3 regions)
MDim eXplorer: https://mitweb.itn.liu.se/geovis/eXplorer/mDim/#story=0 (any spreadsheet data)
Statistics eXplorer embraces a collection of recognized information visualization web compliant methods applied to perform with statistical data including data manipulations and data access methods. Statistics are easily accessed through distinctive and highly interactive visualization.
Statistics visualization of socio-economic information at national or detailed territorial level can provide clear insight on regional differences and performance within a country and comparison of different areas across countries. Statistics eXplorer enables users to explore simultaneously spatial, temporal and multivariate data (both numeric and categorical) from multiple perspectives, to discover interesting relationships, to share their incremental discoveries with colleagues and finally to communicate selected relevant knowledge to other users. Statistics eXplorer is composed of Geovisual Analytics Visualization components facilitating a broad collection of dynamic visualization methods developed and integrated for use with the Adobe Flash and Flex development platform. NCVA provides access to:World eXplorer, Europe eXplorer, Sweden eXplorer and the more general (no map) Mdim eXplorer. You can load your own data (EXCEL data etc.), analyse, gain insight and create your own stories to be shared - see figure below.
Figure: Europe eXplorer with NUTS2 regions showing ageing (65+) population in Europe. Three coordinated and linked views choropleth map, scatter plot, and "fish eye" bar chart. The elderly population have increased fast in Italian regions Toscana and Liguria and represents more than 25% of total population. On the other extreme, in Inner London the elderly population represented less than 10%. In 2015, 35% of the elderly population lived in only 10% of European regions. In Germany the concentration of the elderly population is higher in the old East Germany region such as Dresden. In Poland, Belgium, the Slovak Republic and Hungary the share of the elderly population is much lower. The younger population age 0-14 is represented in the bubble plot on the Y-axis vs. age 65+ on the X-axis and gives an indication of poor coordination between a young generation and retired populations.

Storytelling integrated in Statistics eXplorer
Figure: A Story with snapshots and metadata is created in a Story Editor – The Story is saved and can be shared with colleagues to reach consensus – A Story can be distributed and imported again into eXplorer. Users with diverse backgrounds and expertise participate can participate in a creative discovery processes that transform statistical data into knowledge. After consensus has been reached, the story can be shared through publishing. A snapshot mechanism (see below) helps the author of a story to highlight data views of particular interest, and subsequently guide others to important visual discoveries. The story can then be placed in the public domain to be shared. The snapshot mechanism helps the author of a story to highlight data views of particular interest, and subsequently guide others to important visual discoveries. The final Story (xml format) can then be imported by others with interest in the selected topic.
Publisher for sharing interactive pictures Vislets
Statistics Publisher is our server tool that imports the story produced with Statistical eXplorer. The user selects a layout and visualization tools and then generates the HTML5 code that represents the Vislet. This code is then manually copied and embedded by the user into a web page. The Vislet can be opened in any user’s Web browser and dynamically communicate the story.
You can use our NEW Geovis Portal for publishing your own Vislets. Read more about this at:
Statistics eXplorer visualization methods
Statistics eXplorer facilitates highly interactive information and geographical visualization methods including choropleth maps, bar charts and histograms, table lens, parallel coordinates plots or “profile plots”, scatter or "bubble" plots, scatter matrices, time graphs, treemap, and pie graphs but also flow maps - all methods applied and customized to support large statistical data. They also show hidden data or trends. The distribution plot, (see below) was developed in collaboration with OECD and presents evidence-based facts on regions allowing comparison of regions within countries. Interactive features that support a spatial analytical reasoning process are applied, such as tooltips, brushing, highlight, visual inquiry and conditioned statistics filter mechanisms that help detect outliers.
Learn more about Europe eXplorer
Figure:Europe eXplorer supports three levels of statistical maps - European Countries and 289 NUTS2 regions and 1391 NUTS3 regions. The same variable "ageing population 65+" is here illustrated using the same class limits (12,14,16,19,20%). The visual result differs dramatically when you use NUTS2 regions instead of countries. We see no ageing problems in Spain when using the average value for countries but when NUTS2 regions are visualised, we see that north west Spain has an ageing population. The same for Germany (East) and Italy (North). Learn more about Europe eXplorer loaded with the latest European regional statistics:

Three Visual Methods customized for Statistical Data
Fisheye Lens technique applied in bar charts enhances large statistical data
Our interactive "fisheye barchart" is an example of an useful visual technique that has evolved from Information Visualization. The Fisheye Lens technique magnifies the center of the field of view (Focus), with a continuous fall-off in magnification toward the edges (Context). Degree-of-interest is determined by the level of detail to be displayed assigned through user interaction. The Fisheye Lens, here applied to an interactive bar chart developed by NCVA in 2008, represents an interactive data reduction visualization tool for seeing both local detail and global context of a large number of bars simultaneously. Use the interactive Vislet demonstrator produced from our World eXplorer.

Parallel Coordinate Plot applied to statistical data
The Parallel Coordinate Plot (PCP) is another appealing visualization component introduced and customized by NCVA to the statisticians. Our PCP supports a number of appealing interactive visual analytics methods, for example, to analyze the relationships between indicators and to see a profile for a selected region. Each region (country below) is represented by a string passing through the parallel axes where each axis represents a single indicator, for example, "Population ages 0-14" etc. Differences between highlighted regions can be found by visually comparing the profiles representing them. This has been a highly appreciated method to the statistics community - see figure below highlighting three countries Niger, Qatar and Japan.
A special advantage of the our PCP exploration technique is the capability to dynamically make visual inquiries and filter data. Filtering data is a critical step in the process of statistical data analysis. Filter out uninteresting regions; reduce the data set to a smaller, more manageable size. Each indicator axis has a pair of range sliders which define the bottom and top range for the query area. The range of an indicator can be specified by “dragging” the handles on the top and bottom of the corresponding range slider. Regions with values for a selected indicator, that fall outside of the specified range, are filtered out. A combination of range slider movements can be used to dynamically formulate a more complex visual inquiry. These visual conditions and constraints will immediately reflect the visual contents in all linked views.

Distribution Plot applied to statistical data developed in collaboration with OECD
The Distribution Plot is our own method developed in collaboration with OCD and a variation of the box plot visualization method. It is similar to a vertical bar chart but it excels at showing how data items that belong to a cluster are distributed according to an indicator. Each cluster is represented as one row of dots, and these dots are a representation of each data item belonging to this cluster. The mean value is represented as a thin green line for each country. This component is based on the premise that each data item belongs to a cluster. It is a good way to visualize the differences within a cluster; showing the minimum, maximum and mean value as well as the interval of the values in the cluster. Use the menu on the left side to change which indicator to be visualized and use the green scroll bar on the top to "zoom" in on interesting areas.
Partners using eXplorer and underlying technology
OECD - A successful collaboration since 2008
From an international perspective, our research builds on early (2008) collaborating work with OECD.
Springer paper 2009: Collaborative Web-Enabled GeoAnalytics Applied to OECD Regional Data
Figure: BBC production from 2009
'I have always believed that the very best results in dynamic visualization - the truly breakthrough innovations - are the results of cross-disciplinary collaboration. The NCVA OECD joined project brings together 'right brain' statisticians with the 'left brain' visualization designers. The interactions are incredible!'
OECD Chief Statistician Enrico Giovannini
OECD Regional eXplorer (figure below) is available at:
and the joined development "distribution plot" (figure above) is can be viewed and analyzed at: http://rag.oecd.org/.
OECD started an international interest among the statistical community for our Statistical eXplorer with integrated Storytelling. OECD reported more than 10,000 users of OECD eXplorer at their web site during the first couple of weeks.
Figure: Regional eXplorer, Metropolitan eXplorer and Factbook eXplorer were customized by NCVA for the OECD web site
Figure: Regional eXplorer "ageing population in regional TL3 Europe" An emerging and challenging statistical application domain is geovisualization of regional (sub-national) statistics. Higher integration driven by institutional processes and economic globalisation is eroding national borders and creating competition along regional lines in the world market. Sound information at sub-national level and benchmarking of regions across borders, therefore, has increased in importance in the policy agenda of many countries.
Figure: "The Organization for Economic Co-operation and Development (OECD) makes a lot of world indicators available (e.g. world population and birth rate). Much of it goes unnoticed, because most people just see a bunch of numbers. However, the Factbook eXplorer from the OECD, in collaboration with the National Center for Visual Analytics, is a visualization tool that helps you see and explore the data" http://stats.oecd.org/oecdfactbook/#
Collaboration with Eurostat and European Commission
Another important user of NCVA/NComVA technology is the European Commission that have used Statistics eXplorer since 2009 for internal analysis of Eurostat statistical data.
The application analyses regional statistical data for European at both NUTS2 and NUTS3 level, grouped into different statistical domains. Using the interactive map, individual regions can be selected while different visualisation methods allow the comparison and analysis of regional data in a user-friendly analytical way. The animated timeline shows how regions have performed over time.
Figure: Regional Statistics Illustrated here with latest "Unemployment rates" 2014 contains different dashboards, which always feature a choropleth map on the left pane. On the right window, the user can select four different views:

Statistics Sweden SCB
NCVA started its collaboration with SCB already in 2004. SCB provided statistical data and professional advice. The first Statistikatlas was installed at SCB in 2010. For more information see:
Figure: Sweden has an ageing population. The average age has increased from 37% in 1968 to 41% in 2014. The amount elderly population 65+ has increased from 13% to 19.6% during the same period. This interactive picture is available at:
The Flow Map eXplorer Trade Demonstrator
The data which represents a movement from an origin to a destination is defined as flow data. There are many examples of flow data including commuting, migration, trade and flows of money that have drawn much attention of policy makers, city planners, researchers and ordinary citizens as well. This kind of data is two-dimensional relationship data; thus, it is normally large.
NCVA introduces an interactive Flow Map eXplorer demonstrator based on a large OECD Trade data set that effectively can explore spatio-temporal and multivariate trade statistical flows (Export and Import) data using bidirectional flow arrows where both in-coming (import) and out-going (explort) flows can be clearly shown. This applied research task is based on a collaboration between OECD and NCVA.
The Trade Flow Map eXplorer demonstrator provides interactive trade flow visualization of the OECD countries based on two flow types (Import, Export) for more than 4000 commodities, 21 time-steps and more than 200 countries. The flow interaction data table for only one focus point represents more than 1GB. The large trade data is cut into smaller more manageable data files, providing true interactive performance , where each interaction data table represents an origin point (for example, USA below), a combination of a destination points (countries) , selected commodities and all 21 time-steps. The reason of this data management is that normally a user needs to focus on 1-5 selected origins (countries), a few selected commodities but wants to analyse the data of all flow types (compare import and export), for all time-steps (to find pattern over time) and from/to all countries (to find the biggest flows).
Figure: The Flow Map eXplorer based on OECD trade data demonstrator with the Origin USA and all countries as Destination showing Total Trade (import, export and Net) for 1988-2008.The map shows flows for the "Top 10 Flows" and the bar chart shows Total "Export", "Import" and "Net" for all countries.
The Trade Flowmap demonstrator is available at http://mitweb.itn.liu.se/GAV/flowmaptrade/

NCVA started Research related to Storytelling already in 1999 called "SmartDoc"
SmartDoc was our first implementation of Storytelling and integrates interactive and collaborative visualization into reports in MS Word format. The normal contents of a report, text and images, are extended with interactive 2D/3D visualization. Data and bookmarks are integrated into the document structure, which make the SmartDoc just as easy to handle as a traditional document. The reader is given a more active role and can interact with the embedded data in order to gain a better understanding of the report’s contents. First publication:
Jern: “Smart Documents with ActiveX 3D Data Visualization Components”, reviewed article in “Digital Media: The Future”, Vince J. A., R. A. Earnshaw (Eds), Springer Verlag March 2000, ISBN 1-85233-246-8.
As social creatures, we love telling stories and sharing them in a good laugh with others. It doesn’t matter how dry or boring the subject inherently is. If someone can tell a good story, others will listen and enjoy it. Analytics visualization experts are challenged to elicit a strong engagement and wonder in our stories stimulating the readers’ curiosity making them want to learn more and convey a deeper meaning.
A picture is often worth a thousand words, an interactive visualization is worth a thousand pictures but interactive storytelling provides the true difference and that is "understanding" and "knowledge"
A storytelling mechanism assists the author to improve a reader’s visual knowledge. Authors can develop interactive educational material based on the 4Ws concept “What-When-Where-Why”. A story is composed of texts and visual representations together with snapshots, metadata, hyperlinks and references providing answers to the classical 4Ws questions (see figure below): “What” is the data? The data are shown for a given time step - “When”? Moreover time series can be viewed interactively and simultaneously in the in the linked graphs; “Where” is mostly considered in regional comparisons. “Why” is the most important aspect of the story and explained in the metadata text section together with snapshots and hyperlinks that enable users to further analyse aspects related to topics and are helpful tools for both specialised and non-specialised users.
Figure: Interactive educational statistical material based on the 4Ws concept “What-When-Where-Why”
Figure: Our storytelling mechanism is used by the author to: 1) import regional statistical data; 2) explore and make discoveries through trends and patterns and derive insight - gained knowledge is the foundation for 3) creating a story that can be 4) shared with colleagues and reach consensus and trust. Visual discoveries are captured into snapshots together with descriptive metadata and hyperlinks in relation to the analytics reasoning. The author gets feedback from colleagues, adopts the story and 5) finally publishes “tell-a-story” to the community using a “Vislet” that is embedded in blogs or Web pages. See example of a Vislet embedded into a web site below.
Embedding interactive visualization in web sites
The interactive picture below provides insight into several key statistical indicators covering world countries during 1968-2014. We suggest that you start reading the storytelling text below the interactive picture and click on the snapshots buttons or the red text (snapshots). The geographical world countries are rather big and loading could take some time. You can reduce the map window to the left to see 100% of the scatter and bar chart. Or go to the Vislet web site:
Interactive Figure: World eXplorer with 3 time-linked views showing indicators related to countries of the world “ageing population in world” during 1960–2014; map, scatter plot (age 65+ vs. age 0–14) and bar chart; comparing 4 countries Niger,Germany, Sweden and Japan. Students learn interactively that Japan maintains highest elderly rate, while Niger has the lowest. The students can interact and change indicators (many other indicators are available in this story) to discover reasons behind this trend and gain knowledge.

Treemap implementation with bubbles and bar chart
A potential Swedish sales management data is stored in EXCEL data and can be imported direct into MDim eXplorer. The data has five categorical data columns (Sales person, Sales Manager, District, Gender and Age group; and four numerical data columns). The sales data is here represented with a treemap and fish eye bar chart. Red colour indicates negative sales results (column H). The treemap is divided into "Districts" (Column C) and the "Sales person name" (Column A) is shown. The size of the rectangles are related to "Total Sales" Column F. The combination of the treemap and bar chart provides a deep insight into this kind of abstract data. More information: http://ncva.itn.liu.se/explorer/mdim-explorer?l=en
This treemap visualization shows hierarchies in which the rectangular screen space is divided into several hundreds rectangles. Each rectangle represents a sales person in a hierarchy. The colourful presentations accommodates hundreds of sales management data items in a meaningfully organized display allowing patterns and exceptions to be spotted immediately. Combining a treemap visualization with, for example, fisheye bar chart makes the two linked and coordinated views powerful.
The picture below is a "Vislet" produced in HTML5 analyses the Swedish sales management data above. The Vislet was created as an story example produced with MDIM eXplorer and then inserted into a blog site:
This colourful presentations accommodates hundreds of sales management data items in a meaningfully organized display allowing patterns and exceptions to be spotted immediately. The size of the rectangle refers to "Total Sales" while the colour attribute represents "Sales result %".
When the colour and size dimensions are correlated in some way with the tree structure, one can often easily see patterns that would be difficult to spot in other ways, such as if a certain colour is particularly relevant.
Visual Storytelling in Education - VISE Project
Statistics eXplorer is applied in our research project that focuses on learning based on Knowledge Visualization and Geovisual Analytics Statistics in the VISE (Visual Storytelling in Education) research project. VISE supports the use of learning for these focus areas:
The visual storytelling process available in “Statistics eXplorer” will be applied to improve the students knowledge and understanding of sophisticated statistical relations. Teachers will be able to, individually and together, develop a dynamic teaching material through storytelling, through the web. Students will be able to, with help of powerful geographical statistics, explore statistical relations on their own. A better understanding of how educators and their students can elicit deeper user understanding and participation by exploiting dynamic web-enabled statistics visualization is of importance. Together with the associated science of perception in learning in relation to the use of multidimensional spatio-temporal statistical data this will contribute to the research fields of Geovisual Analytics as well as educational science.
Other NCVA Research Projects
NCVA and from 2010 spin-off company NComVA have collaborated with statistical organisations including SCB Statistics Sweden, OECD Paris, Eurostat, Norrköping Kommun, Linkoping Kommun and Göteborg Stad. But also industrial Ericsson Research in Linkoping and financial support for two industrial PhD students was provided by Unilever Research Port Sunlight UK and Swedish SMHI (Swedish Meteorological and Hydrological Institute) Norrköping, and several European universities. Our visualization tools has during 2006-today helped these organizations to better understand the evolution of applying information visualization and geovisual analytics to multidimensional and multivariate data.
VINNOVA: "En forskargrupp på Linköpings universitet har i samarbete med bl.a. OECD, SCB, SKL, Danmark Statistik och Göteborg Stad utvecklat revolutionerande interaktiva "berättande" visuella metoder (storytelling) som enkelt kan publiceras i media som bloggar eller integreras i Web sidor och spridas till miljoner läsare genom bl.a. en annan samarbetspartner engelska tidningen Economist. Istället för en statisk bild så publiceras interaktiva bilder tillsammans med en förklarande text. Läsaren kan också själv interagera med visualiseringen och därmed kanske bättre förstå hur författaren har tänkt. Forskningsprojektet som bl.a. finansierats genom KK-stiftelsens visualiseringsprogram har vid flera utvärderingar demonstrerat en världsledande teknologi"
