[techniq]

Beginning support / example: https://codesandbox.io/s/njvoqwj24

Based on d3-sankey-circular, although d3-sankey-diagram had some nice features

[techniq]

Been tracking the progress of d3-sankey-circular in hopes to only use it for both circular and non-circular sankey layouts, but just logged an issue regarding handling of nodePadding and general layout.

Hi, how's going about this issue? Maybe I can provide some help if needed, because I'm familiar the d3-sankey API. 😆

BTW， I think sankey diagram designed for flow data, and flow data generally is non-circular. 👀
