Re: VTK for visualizing 3D Networks

Hi Benny,
Have you seen this?
https://www.westgrid.ca/events/westgrid_online_workshop_3d_graphs_networkx_vtk_and_paraview
It certainly shows that what you want is possible....
I'd also advise looking at more of the VTK examples - I think there's a
Glyph Mapper which will change the size/color of the spheres based on a
data value for you.
HTH,
Aron
