Multi-part sankey?

[mbostock]

Is this different than giving as input a graph where there are multiple links between the same pair of nodes? For example:

sankey({
  nodes:[
    {name:"A"},
    {name:"B"},
    {name:"C"}
  ],
  links:[
    {source:0, target:1, value:100, color: "red"},
    {source:0, target:1, value:80, color: "green"},
    {source:0, target:1, value:50, color: "blue"},
    {source:0, target:2, value:50, color: "red"},
    {source:0, target:2, value:40, color: "green"},
    {source:0, target:2, value:20, color: "blue"}
  ]
})

Which might look like:

The thing I could imagine that’s missing is a constraint that the links are drawn in a certain order.

Pretty sure I made it because I thought the sankey layout didn't support parallel edges. It's been a while, if there was another reason and I remember, I'll post it, otherwise yeah, just the ability to determine draw order would be useful.

It occurs to me that the requested feature, then—control over the order of links—was already implemented in #19. Hooray.
