What is VEDAViz?

• A powerful and intuitive web tool for constructing and sharing views of model results.

• Specifically designed for three distinct uses:– Individual analysis– Collaborative analysis– Dissemination

VedaViz is a powerful and intuitive web application for constructing and sharing views of model results. It has been designed to support a variety of uses: individual analysis, collaborative analysis and presentations/dissemination

Basic operations

• Filter– allows filtering of multiple elements from each of the

following dimensions: Scenario, Variable, Model, Region and Year. Can define sets of elements often selected together.

• Configure– Any dimension can be: put on x-axis, summed over, used

for small multiples or put on separate tabs• Render

– Several predefined chart types, or even in tabular form (pivot table), which can be downloaded to Excel

Analysis with VEDAViz

• Slice and dice using conventional charts (interactive)• Box plots• Scatter plots and animated charts• GIS capability

– Trade flows– Regional variables on pie or column charts

• Individual establishments (when GIS location available)

– Heat maps (climate results)• Extract numerical data• Save chart images• Unit conversion

Collaboration and Dissemination• Visualizations can be saved as private or public (visible to other

registered users) views• Each view supports a discussion page

• Presenter– Observations can be attached to a saved view– A set of views, along with observations, can be available on a (password-

protected) web link

• Portal– A set of views can be displayed with scenario selections at the bottom,

like the DECC calculator– Relevant mainly when there is a large number of scenarios– Useful even for non-modelers

Conclusion

• It makes direct analysis of large volumes of data, like multi-model/scenario/region results, accessible to people who don’t write their own programs

• For those who do, it can be very useful for picking deep-dive candidates

• Notes– It is designed to be used interactively; not very good to produce images

for documents. I normally use it directly for presentations and use other charting tools on data extracted from VEDAViz for text documents.

– KanORS-EMR is willing to offer this application free of charge for multi-model comparison work in the IAMC community

VEDAViz uses powerful, flexible graphics to facilitate analysis and communication

Relationships rather than Numbers

Several advanced visualizations

• Sankey diagrams, motion charts, box plots, scatter matrix etc.

• Sankey example from Eurostat– Germany in year 2000– Germany in year 2010– What changed?

• Sankey example from TIAM-World climate runs– What changed in 550ppm case over Ref?
