collaboration graph for isosurface generation

Hello Bill Hibbard and the VisAD mailing list,

Does this look like a semi-accurate collaboration graph for
isosurface generation?:

Are there some holes here e.g. classes missing?  Which ones?  It helps me
greatly if i have some sort of a software design to look at.  Suggestions
for improvement would be great!

-cheers, bob
