There are several cross referencing/reference chasing tools, depending on 
precisely what is being attempted.

The old cxref does things statically, i.e. provides a printout.

The gnu id tools provide a general identifier cross referencing tool that 
integrates interactively with emacs/xemacs - these are general purpose tools 
that work well with program sources, particularly C/C++.  They can be driven 
to obtain various types of information from an id database, so could be 
attached to structure drawing tools.

sniff is interactive and nice

The xref-speller  tools by Marian Vittek http://www.xref-tech.com integrated 
very well with emacs/xemacs, lovely tool and my favourite for most of the 
time.  This tool is astoundingly good.  Interactive "follow the reference" 
tool, that understands scopes and can manage multiple main programs in a 
project.  Not sure how they would interact with a diagramming tool, though.

cbrowser.

And many others that escape my recall at the moment.

The tools that integrate with emacs/xemacs may offer a good basis for what 
you want, given the enormous flexibilty of that environment, and the 
undoubted pre-existence of structure collapsing tools.
