// .NAME vtkGraphLayout - layout a graph in 2 or 3 dimensions
//
// .SECTION Description
// This class is a shell for many graph layout strategies which may be set
// using the SetLayoutStrategy() function. The layout strategies do the
// actual work.
//
// .SECION Thanks
// Thanks to Brian Wylie from Sandia National Laboratories for adding incremental
// layout capabilities.
