reproduce profile with animated flame graphs

I read the blog post and found it very relatable:

It would be awesome to have animated mode where one could select a range and then replay either step by step or at some reasonable rate (say 20ms per frame, 10 fps).

Flamegraph "bricks" would then shrink and expand with each "frame". This is effectively watching individual flamegraphs one after another, but with smooth transformations.

Hopefully this makes sense.

Makes sense. We have the data to do that. We could have "step forward" and "step backwards" buttons. Imagine selecting one second, then being able to step forward by one second at a time.

The D3 plugin already supports that and I probably have a script to parse the profiles that way. See http://martinspier.io/d3-flame-graph/live.html
