You might also be interested in the vtkGraphLayoutView and
vtkRenderedGraphRepresentation for some ideas on how to render a graph. It
does not have support for moving nodes, but it could give you some pipeline
ideas for how to render a graph with colors, labels, etc. If you call
SetInteractionModeTo3D you are able to have 3D interactions in that view.
