I am trying to generate a diagram similar to that presented by the recent Google Analytics "Visitor Flow". These are also known as Alluvial diagrams.

I can use a web or non-web based solution, as long as I can run it myself.

The data I want to visualize is the following:

  • at time t1, I have x1 units, divided into n1 parts
  • at time t2, the n1 parts split (or merged) into n2 parts, with x2 units
    • i want to show where the splits/merges are taking place.

My data is currently represented with a DiGraph in NetworkX, but this may be irrelevant, since I can output my data in any format required.

Similar to the diagram below
