Box office sales visualization

The Ebb and Flow of Movies graphic at The New York Times displays the box office sales (adjusted for inflation, of course) for popular movies over the last twenty years. I think this is excellent work, but I wanted to see long-term patterns that are easier to see when zooming out (as in this thumbnail). […]

Examples of InfoVis

The Parsons Institute for Information Mapping InfoVis site (“1100+ examples of information visualization”) does have many great examples of InfoVis. You can search or browse through the images (although browsing is done by where the graphic comes from, not the content of the graphic). The site accepts submissions. Found via SimpleComplexity.

Updated Brewer color tables

I have updated the Brewer color tables that I posted last fall. The download includes MG_LOADCT and MG_XLOADCT, which are wrappers around LOADCT and XLOADCT that use the Brewer color tables instead of the default color tables. The update fixes the qualitative color tables. These color tables are for labeling, so they contain 3 to […]

Animated transitions

I saw Jeffrey Heer present his work on animated transitions at IEEE Vis 07. I think this idea has a lot of promise, but I wonder when it’s worth the extra complexity to produce the animation. For most ad hoc analysis, this would not be worth it. But it might be useful for the big […]

IDL Workbench seminar

There’s another IDL event at LASP; this one popular enough to have to be split into two groups. I’m in the afternoon session. See you there! It’s next Thursday February 21, 2008 at LASP in Boulder.

Google hosting scientific data

Google is planning to host a lot of scientific data.

Link via FlowingData.

Information Visualization by Colin Ware

I finally got a copy of Information Visualization by Colin Ware and started reading it. Information Visualization and Readings in Information Visualization edited by Stuart Card, Jock Mackinlay, and Ben Schneiderman are considered the classics in the field of Information Visualization (or InfoVis). In Information Visualization, Ware evaluates visualizations using the scientific methods of psychology. […]
