this is very cool, but...where does one get the data to visualize? Is there a standard for flamegraph data structures?

There appears to be zero documentation on what it needs as input.

Yes, for now I didn't find any standard format of samples dump.

I already figure out how to integrate with golang's pprof, seems I need to work with other perf tools as well.

I am thinking about adding a flag like `--input-format=pprof` for different outputs.
