1 Interactive Statistics Visualisation based on Geovisual Analytics Prof. Mikael Jern NCVA LiU and NComVA AB May Spin-off company to focus on Interactive Statistics Visualization and Storytelling 1

2 NComVA based on 10 years innovative research. Our research centre NCVA was established in 2006 with 1 million in funding from the Swedish Knowledge Foundation; Our Geovisual Analytics technology is developed in close collaboration with in particular OECD and Statistics Sweden - with start in early 2008 but is based on our research since 2002 More than 50 man years development; Statistics explorer V1 for regional data (OECD explorer) and world countries (Factbook) is placed at the OECD public website in October 2008; NComVA AB was founded in May 2010 as a spin-off company from NCVA with involved researchers as shareholders to guarantee a long commitment with continued development and support; NComVA collaborates with organizations interested in leading-edge innovations including OECD, SCB, City of Gothenburg, EC Commission but also Unilever, SMHI, Ericsson Research; Early collaboration with experienced partners 2

3 a picture is worth a thousand words What these numbers could not communicate when presented as text in a table, which our brains interpret through the use of verbal processing, becomes visible and understandable when communicated visually. This is the power of statistics data visualization." Domestic sales larger than International and growing; Flat international sales and decreases sharply in August; Cyclical sales pattern in Domestic sales repeated on a quarterly basis reaching a peak in last month of quarter; 3

4 an interactive picture is worth a thousand pictures Air Pollution in an interactive OECD report Collaboration with Statistics Sweden 4

5 Search + Examine + Explain = SEE to Search for meaningful patterns Discovery then Examine them and once they re found. Gain Understanding and use Storytelling. to communicate meaningful findings to others.. Explain results often in Decisions aha, I see! Collaboration with Statistics Sweden 5

10 From data import, explore and gain insight to storytelling, collaboration and publishing NComVA offers Statistics explorer applications 10

11 GAV Flash/HTML5 JS framework and toolbox Statistics explorer or Customized Applications 11

12 Integrating GAV JavaScript visual components into QlikView World explorer with Storytelling using multiple linked and coordinates views Why What Where When 12

13 World explorer with Storytelling using multiple linked and coordinates views Why Where Why What When World explorer with Storytelling using multiple linked and coordinates views 13

14 World explorer with Storytelling using multiple linked and coordinates views An improved GUI layout moving frequently used features icons into a top menu and thus more accessible to the user The story writing process Select data, explore, gain insight, create a story, share 14

15 Improved Story Editor Simplified Snapshot assignment add or remove Chapters Snapshot list edit, recapture or delete Snapshot select URL or Snapshot hyperlink to web site new Snapshot Snapshot link Using snapshots to store insights Metatext combined with links to snapshots that has captured the visualization 15

16 Highlight some key innovative technology points: Proven Information Visualization methods ; Highlight some key innovative technology points: Multiple linked and coordinated views explore and see the multivariate data simultaneously from several perspectives; 16

17 Highlight some key innovative technology points: Multiple linked and coordinated views explore and see the multivariate data simultaneously from several perspectives; Highlight some key innovative technology points: Dynamic Colour Legend - facilitating statistical methods for class value calculations and scientifically tested perceptual acceptance of colour scales and a filter mechanism attached to legend; Migration net flows 17

18 Migration Net Flows Europe in Colour and B/W Red means negative Flow and Blue is Positive Highlight some key innovative technology points: Dynamic Queries using the Indicator Filter Find outliers (percentile 10% and 90%) for age group

19 Highlight some key innovative technology points: Fish eye technique to See selected larger data set within their context Dynamic Bar Chart Viewed from the front, some items are in focus, but all items are present in a bird s eye view Highlight some key innovative technology points: Fish eye technique to See selected larger data set within their context Dynamic Bar Chart 19

20 Highlight some key innovative technology points: Focus & Context technique to See selected larger data set within their context Table Lens Highlight some key innovative technology points: Focus & Context technique to See selected larger data set within their context Choropleth Map 20

21 Highlight some key innovative technology points: Focus on areas of interest, while maintaining surrounding context (but not in as much detail). Give more space and attention to focus but keep context Fisheye views: geometric distortion like a magnifying glass over the area of interest Overview and detail: an overview map complements a detail map view. Focus & Context requires Interaction Highlight some key innovative technology points: Parallel Coordinates or Profile Plot age 0-14 age age 65+ life expectancy fertility rate GDP growth Max Niger Japan Niger China China Sweden Germany Japan Min 21

22 N equidistance axes correspond to the variables Axes are scaled to the [min, max] range of the variable Every data item (country) corresponds to a polygonal line age 0-14 age age 65+ life expectancy fertility rate GDP growth Niger Max Japan Niger China China Sweden Germany Japan Min Highlight some key innovative technology points: Parallel Coordinates with applied Filter Mechanism - Countries with highest Health Expenditure per capita; USA Denmark Finland 22

23 Highlight some key innovative technology points: Scatter Matrix - Information Visualization technique to explore multivariate data Highlight some key innovative technology points: Treemap Visualization in linked views 23

33 Highlight some key innovative technology points: Data Complexity in Statistics Visualization Quantitative and Categorical data Quantitative data (Numerical) e.g. 10,000; 2; 121;... Real numbers (e.g. object A is twice as big as B, can do arithmetic; Categorical data (Nominal) Labeling function e.g. Continent Europe, Asia, Africa; Category data that can be direct compared e.g. High, Low,..; Working with Categorical data in World explorer Human Development Indicator (HDI) Categories: Low HDI, Medium HDI, High HDI, Very High HDI 33
