Google Analytics API on App Engine Treemap Visualization [analytics.blogspot.com] is an alternative look at your Google Analytics data in the form of an interactive treemap visualization. One can even allow the application access to your own Google Analytics data, to create personalized versions of the treemap.

The data that is displayed originates from the last 14 days of data in the selected Google Analytics profile. Each rectangle represents a unique landing page, with its size linked to the traffic to the page (i.e. entrances), and the color representing the bounce rate (i.e. green is Good: low bounce rate, red is bad: high bounce rate).
