for existing codebases, doxygen will produce static call graphs for c/c++ and java codebases using dot graphs that are hyperlinked back and forth to lxr style code listings (you do typically have to turn this on as it's expensive to compute and is turned off by default.) i always found uml and other object style diagrams to be kind of obfuscating and encouraging of overcomplicated oop designs.
