Your diagram appears to be a call graph, not a flow chart.
A call graph like this can be a useful piece of documentation. A
bigger challenge in some parts of Maxima is that communication among
functions often happens through shared variables as well as through
the function calling mechanism.

PS I am of course using the word "function" in the Lisp sense, not in
the mathematical or functional-programming sense. Lisp functions can
have side effects.
