The Tree Map Diagram visualizes the distribution of numeric values with the help of the area of rectangles. 


Upon initial opening, a Tree Map Diagram with a last used or default configuration is presented. All further configuration is done interactively on the diagram. Use the toolarea in the top left corner of the screen to configure your diagram step by step.

Currently the complete diagram configuration is stored in the browser URL. You might want to use your browsers bookmarking functionality for saving the configuration.
