Detailed Description

abstract superclass for all tree map layout strategies

All subclasses of this class perform a tree map layout on a tree. This involves assigning a rectangular region to each vertex in the tree, and placing that information in a data array with four components per tuple representing (Xmin, Xmax, Ymin, Ymax).

Instances of subclasses of this class may be assigned as the layout strategy to vtkTreeMapLayout
