Description
Treemaps display hierarchical (tree-structured) data as a set of nested rectangles. Each branch of the tree is given a rectangle, which is then tiled

with smaller rectangles representing sub-branches. A leaf node's rectangle has an area proportional to a specified dimension on the data.

(Description from http://en.wikipedia.org/wiki/Treemapping)

In specific Add method override, AValue represent node's value, Text represents node's text and Superior node's parent.

Few rectangle tiling mehtods are also available.
