Jeff,

Very cool! This visualization is fantastic! I made a demo of it here:
http://www.vtk.org/Wiki/Visualize_a_graph

The connected component filter is exactly what I wrote yesterday, dang...
haha I guess we'll call that one a good exercise for me.

I also made an example of this:
http://www.vtk.org/Wiki/Find_Connected_Components

Now that I have some nice tools I'll go check out my real problem...

Thanks,

David
