I know nothing about GraphViz, just looked at the site.  It would
seem that there is a "companion" system, DOxygen 

  http://www.stack.nl/~dimitri/doxygen/index.html

that seems to parse C++ and produce output for GraphViz.  
Have you tried it out?

Yuk indeed.  

You are only going to look for certain patterns in the
C++ code, right?  That is not so bad with a suitable 
parser/lexer combination.  You will have to write a 
grammar that can handle the concepts you want to extract.

I can suggest the LL(1) Ruby scanner/generator that I 
have written called CocoRb.

 http://raa.ruby-lang.org/list.rhtml?name=coco-rb

You won't be able to parse the complete C++ tree, though
you should be able to extract wht you want.  And it is
pretty easy to use.  There are some sample of scanning
C code and processing it that may be of interest.

Regards,
