I don't think there are any.  The issue is, how do you want to do that? 
  Since you have no type information you cannot generate this graph - or 
the graph will be so large that most branches are never traversed.  For 
example, what do you expect such a tool to output for this:

def f(x) x.to_s end

Basically, since you do not know what x will be you have to put in all 
classes #to_s method etc.  Am I missing something?

Kind regards
