// .NAME vtkTreeMapLayout - layout a vtkTree into a tree map
//
// .SECTION Description
// vtkTreeMapLayout assigns rectangular regions to each vertex in the tree,
// creating a tree map. The data is added as a data array with four
// components per tuple representing the location and size of the
// rectangle using the format (Xmin, Xmax, Ymin, Ymax).
//
// This algorithm relies on a helper class to perform the actual layout.
// This helper class is a subclass of vtkTreeMapLayoutStrategy.
//
// .SECTION Thanks
// Thanks to Brian Wylie and Ken Moreland from Sandia National Laboratories
// for help developing this class.
//
// Tree map concept comes from:
// Shneiderman, B. 1992. Tree visualization with tree-maps: 2-d space-filling approach.
// ACM Trans. Graph. 11, 1 (Jan. 1992), 92-99.
