Dimensions Treemap using Protovis

Based on Treemap from protovis design in javascript, I have now a treemap with 3 dimensions.

Click on the image below to see it in action (because my post does not allow it to be dynamically displayed).

3 Dimensions are:

1. definition of groups that share the same kind of color
2. each square with it's area
3. each square is more or less dark and more or less saturated

This is something that you I use to display a status of issues on a bunch of projects. For instance we develop several keyboards and mice at the same time.

1. The yellow group of color could group all keyboard projects.
2. square area is proportional to the total number of bugs for this project
3. square darkness and saturation/alpha is proportional to the number of open bugs for this project

An enhanced TreeMap Applet

TreeMap is a way to present information that is very efficient sometimes...
This TreeMap Applet has been enhanced with custom colors and comments using 2 additional xml fields to the standard xml description:

• details for comments when clicking on squares.
• hue / color for discriminating between main groups of squares.

The java applet code is based on http://www.objectlab.co.uk/open original JTReeMap code.

freemind and treemap

Has anyone done some roundtrip transformation from freemind to treemap to freemind?

That would be way cool.
