I almost never find graph usage useful, TBH (and flamegraphs are worse than useless). And perf's support for stack traces is always wonky _somehow_, so it's not easy to find good defaults for the cases where I need them (I tend to switch between fp, lbr and dwarf depending on a whole lot of factors).
I think I've only been able to get good call stacks when I build everything myself with the right compilation options. This is a big contrast with what I remember working with similar tools under MSFT environments (MS Profiler or vTune).
