requirements:
similar to this diagram, it indicates that something flows to the specified node A (single point, user-specified single point), and data flows out of the specified node A.
question:
is there a picture library that meets this function? I have tried to use the tree map of d3, but by default, the tree map only has one root node diverging to one side, and I try to change the divergence direction through parameters, but the tree view is a tree map after all, which does not conform to the relationship of n-> 1-> n
. I would like to ask you what map can meet my needs, pick out the plug-in used in the following figure is better!
