this one’s about treemaps aka space constrained visualization of hierarchical data . treemap is shorter :) what is it ?Open Source Flex Component: TreeMap 2.0 (Beta)
After quite a bit of work, I’m relieved to present a beta release for the next version of my TreeMap component for Flex .
The Treemap 4.0 Demo is a Java Applet and requires your browser to have the Java 1.4 plugin.

Squarified Treemaps with source !! | code zen
Treemaps (sometimes called heatmaps) are one of my favorite data visualization techniques, and it has taken me a while to finally figure out how to do them. The idea is simple: Each component is represented by a rectangle whose area is proportional to the ‘weight’ or relative importance of the item. I finally did find a technical paper on the idea and have implemented it in my source code. The algorithm efficiently finds what the best dimensions should be for the rectangle keeping its length-to-width ratio as close to one as possible.
