You get reasonably decent call charts from profilers.
Many IDEs include a profiler or support third party profiling, with call charts. Or you can use a standalone profiler which understands the relevant debug info.
An advantage of using profiling is that you get dynamic insight into what may be relatively obscure control flow linkages. The disadvantage, of course, is that it's not complete, if your profiling run didn't include the call, it won't be in the tree.
