I need to be able to render Sankey diagram with cycles as well.
I see some implementations drawing links in the opposite direction as well as duplicating nodes so that it becomes DAG.
(a.g. drag A->B->C->A with node A displayed twice)

你好，子数据 指向 父（及以上）数据的情况是什么意思呢？
什么情况下会导致数据存在这样的问题呢？
这个数组格式是我这边自己编辑的。没有做过任何的处理的。

您好，我在和您确认一下，是不是所有的桑基图都不支持环形布局？

I don't know if I understood everything because I've just ran it though google translate, but wouldn't it be possible to add it as a feature request to allow cycles in the Sankey diagram?
Is there any definition which says a Sankey diagram must be acyclic? I don't think so, and there are many examples online for Sankey diagrams with cycles. Also, it should be technically possible, as there are cyclic Sankey diagrams e.g. for d3.js.
So while it is not possible now, maybe the cyclic support could be added in the future?
