The info vis support of VTK is weak at the current time.  While the general 
representational structure is there (i.e., "fields"), the algorithms are 
scarce. Beyond the graph layout filter, there is a 
vtkParallelCoordinatesActor class. You can also subsample n-dimensional 
data into 2D or 3D and use filters like Delaunay triangulation or 
ShepardsMethod to construct a reduced dimension dataset and then visualize 
that.

Some folks have created extensions to VTK for InfoViz. In particular, you 
might want to see what David Duke has done www.cs.bath.ac.uk/~djd/vtk.html. 
If you do anything with this I'd like to be kept informed.
