Flex TreeMap Component Open Source Flash
A treemap displays hierarchal data in a truly fascinating way. Using a limited rectangular space, a series of nodes display relationships between items through easily-visible properties such as size and color. Furthermore, by structuring your data into categories, you can discover similar relationships on multiple levels and navigate your data in a way that you previously hadn’t imagined.
The Flex TreeMap component works with data much like the standard Tree component. Simple XML and Object structures are handled by default, but advanced data descriptors may be used to understand any sort of hierarchal data. Custom node and branch renderers can add useful new functionality. Styles and skins can customize the look and feel of the component to fit into any application.
