Saw Ben Shneiderman present for an hour today at Tufts on information visualization. Will post much more from the notes I took in the coming days. Did see this cool application of Treemaps for representing news articles from (i presume) google news though: http://www.marumushi.com/apps/newsmap/newsmap.cfm
Everyone’s probably seen that already, but I’m always the last to know 🙂
Another news map that isn’t as pretty, but is more interactive is here, and a few other consumer applications of treemapping can be found by the hive group here.
