VisWeek 2008 Live-Microblog
A live-blogging experiment from the VisWeek 2008 trio of conferences (InfoVis, VAST, Vis) in Columbus, OH.
And so it begins ...
by Robert Kosara, 2008-10-19The annual gathering of the InfoVis family has begun. Lots of familiar faces. One change from the previous years: there is no conference bag. I actually think that that's a good thing, because I tend to not use them (they're usually small and not the prettiest or sturdiest) and just throw them away after a year – when I get the next one.

Papers Fast Forward Starts with a Bang
by Robert Kosara, 2008-10-19Wow, the Papers Fast Forward starts with a bang! Extremely well done "movie opening" for the best paper, certainly the most elaborate paper preview I have ever seen. Jeff Heer also did a great job with his minimalist list of quotations (and no talking). Caroline also did a great cliffhanger-style preview of our paper. Looks like it's going to be an interesting few days.

Yay! Best Paper Honorable Mention!
by Robert Kosara, 2008-10-19I knew this was an awesome paper. We're one of three Honorable Mentions for the Best Paper Award. Miss Caroline's talk in the Design session tomorrow at your own peril!

An Interesting Take on Scatterplots
by Robert Kosara, 2008-10-19The Best Paper by Elmqvist, Dragicevic, and Fekete has an interesting take on using 3D transitions for navigating scatterplot matrices. The target audience is also people not too familiar with visualization, though I think this would still overwhelm them. The actual navigation between cells isn't improved, and Georges Grinstein made a valid remark about the cognitive load when switching between 2D and 3D. But it's good to see more animation for navigation, Robertson et al.'s paper later will also be interesting.

Interaction with Probes
by Robert Kosara, 2008-10-19I'm pointing to UNCC work again, but I'm liking this more and more. Tom Butkiewicz presented his work on using probes to query simulations on maps (PDF). This is a good approach to multiple views and allows a lot more useful insight by seeing and comparing local effects. Well presented, too!

Distributed Cognition for InfoVis Theory
by Robert Kosara, 2008-10-19, 2 commentsCriticism of the sad state of theory in InfoVis. Yes! Zhicheng Liu presented work he has done with Nancy Nersessian, John Stasko. His take on internal and external knowledge and the way they can be applied in InfoVis is a great basis for further work. He also quoted from our paper (yes, another link to our stuff, but what can I do?). Stasko and his students have been doing some excellent foundational work in the last years, it's great to see that.

Those Who Forget History ...
by Robert Kosara, 2008-10-19Heer's work on history management in Tableau is interesting. There seems to be a lot of interest this year in recording sessions and using that information for various purposes. Good extension of long-standing work in HCI – I wonder when this will make it into the program.

Who Votes for Donut Charts?
by Robert Kosara, 2008-10-19, 1 commentJohn Peltier would be jumping up and down if he were here, seeing Geoffrey Draper present his work on visualizing exit poll data. He's using what is essentially a donut chart for the data. The interaction is not bad, but the visualization is really close to useless. You can't see different subsets at the same time, and the donut makes comparing between different categories difficult. There are much better ways to show this kind of data, like Parallel Sets. Their goal was for this to be useful for non-experts, which it undoubtedly was – but I wonder if a better visualization might get close in that regard and still be a better visualization.

InfoVis Contest 2.0
by Robert Kosara, 2008-10-19When I complained some time ago about the sad state of the InfoVis Contest, I wasn't kidding. We just presented the single submission we got (Patrick Gage Kelley and Daniel R. Rashid), who got an Honorable Mention. I'm stepping down as a co-chair after my two years, and the team of Petra Isenberg (who is new), Bongshin Lee, and Jing Yang are changing the contest to an exhibit. They will no longer publish a dataset, but rather ask for submissions of interesting insights gained with visualization tools. They want to collect a portfolio of uses of InfoVis, which should be interesting.

Visualization Literacy
by Robert Kosara, 2008-10-19The best poster this year is by Maria Velez et al, and addresses visual and visualization literacy. Their study looked at the problems people have with visualization to understand how they can transfer knowledge about one visualization to faster understanding of another. This is a very important topic, and it's great to see some work in this area; I hope this will be a paper next year.
