I'll just add that having a tool visualizing this would be very useful
for refactoring code. If you e.g. use color to distinguish
nodes/functions from different modules, you could use that information
to decide to merge or split modules to minimize external interfaces.
You could also try to automatically cluster nodes, which would be more
interesting theoretically, but IMO less likely to be practical.
Another option would be to couple this with profiling or coverage
information to visualize something about the usage of paths and nodes
in the call graph.
If I haven't seen further, it is by standing in the footprints of giants
