That makes sense. The trace module, which, I must confess, is new to me,
mentioned by Vasudev looks like exactly what you need. It should be
simple to instrument your code with that module, get the call graph and
then use graphviz or some similar tool to draw a picture of it.

Of course. Different strokes for different folks.
