2. 25 May 2005 KICP Viz 2005 What do we mean?  Making interactive 3d graphics should be as easy to do as making static 2d graphs  Nothing to install  No graphics programming  No funny formats (straightforward formats ok?)  Does not have to deal with large datasets - 100 000 points ok

3. 25 May 2005 KICP Viz 2005 What do we mean?  Does not have to be optimal - just has to be ‘good enough’  Ideally, web interface Get your data in text files (csv, etc) Upload data Get a drink Get a zip file (or vrml? X3d?) Unzip zip file Click (prayer not required)

4. 25 May 2005 KICP Viz 2005 Examples already out there  Large Graph Layout : Adai et al, 2004 Bioinformatics Provide nodes + edges  returns VRML  Holodraw : Simkin, 2001-5 Provide set of points, etc  returns VRML Not online yet, would be easy to make it so  Vermalizer : SubbaRao & SubbaRao, 2004 Give points, get VRML (applied to SDSS queries)

5. 25 May 2005 KICP Viz 2005 Questions  Why aren’t more of these services available?  Are these services of any use at all?  Would anyone use them if they were available?

6. 25 May 2005 KICP Viz 2005 More Questions  What kinds of inputs would these services handle?  Do the visualization techniques required to support these services exist?  How do you trade-off flexibility vs usability?

7. 25 May 2005 KICP Viz 2005 Prototype: Ndaona  Experiment in creating Partiview files in Matlab positions + glyphs + edges  scatterplots+graphs  Why Partiview? Fast, interactive To stop people in my department bugging me to make them pretty pictures  Why Matlab? Standard package in my research community Great for prototyping

10. 25 May 2005 KICP Viz 2005 Conclusion & Outlook  Is this a waste of time?  What formats are required?  Who should host this?  GUI : programmable? (hello, Toshi…)
