Recently I developed a FlameGraph for Angular, which might come handy. You can find the component here [https://ngx-flamegraph.firebaseapp.com/].

> Support for CPU FlameGraphs in new web UI
> -----------------------------------------
>
> Key: FLINK-13550
> URL: https://issues.apache.org/jira/browse/FLINK-13550
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / REST, Runtime / Web Frontend
> Reporter: David Morávek
> Assignee: David Morávek
> Priority: Major
>
> For a better insight into a running job, it would be useful to have ability to render a CPU flame graph for a particular job vertex.
> Flink already has a stack-trace sampling mechanism in-place, so it should be straightforward to implement.
> This should be done by implementing a new endpoint in REST API, which would sample the stack-trace the same way as current BackPressureTracker does, only with a different sampling rate and length of sampling.
> [Here|https://www.youtube.com/watch?v=GUNDehj9z9o] is a little demo of the feature.
