[Feature] Can ECharts 5 support Chord with weighted ribbons?

[carrgilson]

What problem does this feature solve?

Previous versions of ECharts has Chord diagram examples displaying ribbons with varying sizes, weighted to their data values.

@sjcobb Originally posted https://github.com/apache/echarts/issues/8743#issuecomment-585810703, suggesting the Circular Layout of the Graph diagram is appropriate as a replacement, but that example only displays single pixel line connections, not ribbons with weighted widths.

I see that issue is requesting the same... @jeffersonswartz Requested this in ECharts 3 in https://github.com/apache/echarts/issues/10098 @linxingyun Requested this in ECharts 4 in https://github.com/apache/echarts/issues/8743 @ataft Requested this in ECharts 5 in https://github.com/apache/echarts/issues/8743#issuecomment-901491087_

What does the proposed API look like?

If examples that mirror the following could be produced, that would be great: https://datamatic-public.github.io/echarts-2.1.10/doc/example/chord1.html#-en
