Ah ok, I see what you mean know. I parsed too quickly the gprof documentation.

Yep, may be we can implement such layout mode too, or at least getting it through kcachegrind.

Having support for perf callgraph format in this:
http://code.google.com/p/jrfonseca/wiki/Gprof2Dot

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)
