Just noticed the following blog post from Brendan Gregg:

Neat! Since it turns out the NodeSource N|Solid CPU profile displays those three visualizations.
You can find out more about generating CPU profiles for your Node.js apps using N|Solid by reading the documentation. But also read Brendan's blog above for some rationale on the different views.
The graphs below are from the same CPU profile, and all have the function getThreshold()
selected, which appears green in the graphs.

Sunburst
