abstract superclass for all graph layout strategies
All graph layouts should subclass from this class. vtkGraphLayoutStrategy works as a plug-in to the vtkGraphLayout algorithm. The Layout() function should perform some reasonable "chunk" of the layout. This allows the user to be able to see the progress of the layout. Use IsLayoutComplete() to tell the user when there is no more layout to perform.

This is the layout method where the graph that was set in SetGraph() is laid out.
The method can either entirely layout the graph or iteratively lay out the graph. If you have an iterative layout please implement the IsLayoutComplete() method.
