Alluvial-Growth.js or Sankey That Grows

While alluvial/sankey diagrams may be useful for showing how finite resources flow through a closed system the traditional implementation cannot show any sort of change whether it be growth or decay between nodes. Alluvial-Growth seeks remedy by allowing the creator to show growth and decay over time as well as merges and divisions. Built on top of Mike Bostock’s implementation for Sankey this seeks to make a few small changes that create a new kind of graph.

While this is only a first draft I welcome any feedback or criticism.
