[GitHub] [echarts] sedefbostanci opened a new issue #15673: Sankey charts with common nodes

sedefbostanci opened a new issue #15673:
URL: https://github.com/apache/echarts/issues/15673

### What problem does this feature solve?
I want to group the nodes within themselves using the Sankey chart and give a label to those grouped nodes as in the "What does the proposed API look like?" section.
"Transient Stability" and "Voltage Stability" are also nodes with white color and label with bigger font size. They are not connected to any node. I added them to show the chart that I want. The places I want them to be are exactly like that, but of course this order can change from time to time, node places can get mixed up when other nodes that I want to group come. I can do what I want by showing the nodes in the order I added them to the json, I can do this by giving the layoutIterations parameter to 0, but when I do that, a chart like the one below is created, but this is not the chart that I want with all the nodes at top. Actually, I want to make the nodes below Voltage Stability and Transient Stability as two separate trees maybe two seperate sankey chart. I want the common root of these two trees to be the "Risk" node as in example. How can I do such a grouping?
I hope I was able to explain my problem. Thanks.
