A treemap recursively subdivides area into rectangles; the area of any node in the tree corresponds to its value. This example uses color to encode different packages of the Flare visualization toolkit. Treemap design invented by Ben Shneiderman. Squarified algorithm by Bruls, Huizing and van Wijk.
