Treemap visualization

After seeing Nick Mihailovski’s Google Analytics / Protovis mash-up last week, I couldn’t resist playing around with the Protovis visualization package over the weekend.

My first visualization effort is a treemap showing the popularity of sub-categories within DailyMe.com based on Newstogram data for October 2009 (built upon the Protovis treemap example).



The colors represent primary categories, while the size of each sub-category corresponds to its popularity as measured by the ‘Digital News Affinity’ (DNA) score for October 2009.

The search field at bottom of the treemap highlights certain categories / sub-categories (e.g. searching for “sports” highlights the 14 sports sub-categories).

Check out the working demo (requires a modern browser e.g. Firefox, Safari).
