TreeMap Component for Adobe Flex Created by Josh Tynjala

• http://github.com/joshtynjala/flextreemap

Usage Tips:

1. flextreemap uses a defaults.css for maximum compatibility with Flex 4. The default styles and skins only get included automatically when you link the project into your Flex application as a SWC. If you need to make source code changes, you should build a new SWC. See build.xml for details on recommended compiler arguments.

2. Two custom renderers are included with flextreemap. Use them for a more basic looking treemap without gradients.
