Is your feature request related to a problem? Please describe.
Speedscope provides a view that visualizes stack traces in chronological order https://github.com/jlfwong/speedscope#time-order . It looks like a flamegraph samples are not aggregated but rather visualized in chronological order. This usually only allows to see long running functions but provides a good chronological overview over the application which can be useful for filtering

Describe the solution you'd like
It would be nice to select alternative visualizations of the flamegraph and see the callstacks in chronological order.

Describe alternatives you've considered
I can import the perf.data into speedscope
