/**
* @class vtkCirclePackLayout
* @brief layout a vtkTree as a circle packing.
*
*
* vtkCirclePackLayout assigns circle shaped regions to each vertex
* in the tree, creating a circle packing layout. The data is added
* as a data array with three components per tuple representing the
* center and radius of the circle using the format (Xcenter, Ycenter, Radius).
*
* This algorithm relies on a helper class to perform the actual layout.
* This helper class is a subclass of vtkCirclePackLayoutStrategy.
*
* An array by default called "size" can be attached to the input tree
* that specifies the size of each leaf node in the tree. The filter will
* calculate the sizes of all interior nodes in the tree based on the sum
* of the leaf node sizes. If no "size" array is given in the input vtkTree,
* a size of 1 is used for all leaf nodes to find the size of the interior nodes.
*
* @par Thanks:
* Thanks to Thomas Otahal from Sandia National Laboratories
* for help developing this class.
