Having support for perf callgraph format in this:

Or similar callgraph visualization support in perf itself would be nice (including filtering options, highlighting the nodes based on CPU used by given node and the nodes called by it etc).

I really like this. We may indeed want to support it.

Check out the google-perftools' pprof's "gv" command; it's also pretty nice. (although I still usually
prefer kcachegrind's interactive viewer)
