Introduction to a web-based visualization platform which is being used for analyzing results of TIMES models and for EMF multi-model comparisons.

2. 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

4. 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

5. 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

6. 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

7. 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

8. VEDAViz uses powerful, flexible graphics to
facilitate analysis and communication

Relationships rather than Numbers

10. 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?
