This page contains a simple Treemap library for use with Processing It is a minor adaptation of Martin Wattenberg and Ben Bederson's Treemap Java Algorithms collection, released under the Mozilla Public License. Only a small percentage of the original code has been altered from their original library. The reference covers the details.

The Processing library can be found here: library.zip. Unzip the file, and place the treemap folder into your Processing → Libraries folder. Restart Processing if it's already running so that it picks up the new library.
