Function to plot a sankey flow chart with any number of layers and categories.
Based on the contribution of @RomanKuster based in turn on the contribution from @RanranWang, improves them by:
  • Accepting matrix as well as tables with categorical values as input data.
  • Customizable colors (both colormaps or customized matrix).
  • Category labels, layer labels, percentages and legend are switchable.
See demo for data examples.
