How to create a caller/callee graph?

I want to display a 'flow' chart of a process showing time spent in children relative to the parent. For example, say that I have MethodA which calls MethodB and MethodC. 30% of the time relative to MethodA in MethodB and 70% in MethodC. I want to display something like this:

I know this is a sort of vague question, so to narrow the scope, I don't know what kind of chart this might b开发者_开发知识库e. What kind of Libraries might provide the capability to display this type of chart?

I've used Graph# for same purpose - but this is a WPF library. Good news for you is that it uses QuickGraph (http://quickgraph.codeplex.com/) library internally and you can google around that library to see whether there is any code for it to be used as part of winforms.
