Identify D3.js Graph

Question

What is this graph called that was generated by D3.js?

Is there a name for it?

I failed to describe it when looking for keywords in the documentation and spent quite a bit of time scouring the web.

Once identifying it, what is one example in the D3 documentation that includes a graph similar to this? I can't appear to find any that would resemble this.

Answer 1

That is most likely built via the bundle layout.
