// .NAME vtkInteractorStyleTreeMapHover - An interactor style for a tree map view
//
// .SECTION Description
// The vtkInteractorStyleTreeMapHover specifically works with pipelines
// that create a tree map. Such pipelines will have a vtkTreeMapLayout
// filter and a vtkTreeMapToPolyData filter, both of which must be passed
// to this interactor style for it to function correctly.
// This interactor style allows only 2D panning and zooming, and additionally
// provides a balloon containing the name of the vertex hovered over,
// and allows the user to highlight a vertex by clicking on it.
