/**
 * @class   vtkCirclePackLayoutStrategy
 * @brief   abstract superclass for all circle packing
 * layout strategies.
 *
 *
 * All subclasses of this class perform a circle packing layout on a vtkTree.
 * This involves assigning a circle to each vertex in the tree,
 * and placing that information in a data array with three components per
 * tuple representing (Xcenter, Ycenter, Radius).
 *
 * Instances of subclasses of this class may be assigned as the layout
 * strategy to vtkCirclePackLayout
 *
 * @par Thanks:
 * Thanks to Thomas Otahal from Sandia National Laboratories
 * for help developing this class.
