Incubator-echarts: Does echart4 support chord with ribbon?

[linxingyun]

One-line summary [问题简述]

As checked the demo/echarts-examples for echart3/echart4, there is no any demo of ribbon chord.
I found echart2 has demo on supporting ribbon chord. But the demo code from echart2 cannot work in echart3/echart4.
So I got question on whether echart4 can support the ribbon chord diagram? If yes, could you please help to provide a demo to demonstrate it? Thank you so much!

I've got the same question. Chords are very commonly used chart, so having it in ECharts will be very useful!

I've got the same question, I had a solution to support ribbon chord.

you could import chord after import echarts:
import * as echarts from 'echarts'; import 'echarts/lib/chart/chord'
but there is anther question I met, the tooltips was gone.
