Bidirectional relationships #89

Closed arcaweb-ch closed 1 year ago

Hi, loving this library thank you for your effort!

Here is my issue: I have the same elements in both From and To, every element shares data with each other, eg:

[
{"From": "a", "To": "b", "Flow":5}
{"From": "a", "To": "c", "Flow":10},
{"From": "b", "To": "a", "Flow":15},
{"From": "b", "To": "c", "Flow":20},
{"From": "c", "To": "a", "Flow":35},
{"From": "c", "To": "b", "Flow":2},
]

I am trying to put all elements on left and right sides to show relations, like this (sort of): 487118_sankey

Any idea on how to accomplish this?

You just need to use labels, colors etc to make the different sides appear to be same things, while actually being different nodes. https://codepen.io/kurkle/pen/eYvNXqM
