The blog post I mentioned yesterday also has two fine examples of Sankey diagrams done with Mathematica. Nice colorful ones. Black background.

The first one is on cost flows and their distribution onto accounts, expenses, activities, and products (each represented by a column with nodes).

The other is by Sam Calisch (the author of the Mathematica workbook) and visualizes the efficiency of energy use in Australia.

Actually this second diagram is made up of two Sankey diagrams: the main one for Australia, the overlay one with the values for New South Wales. A cool idea to show the share of NSW.

The author of the post at visualign says that he “wouldn’t be surprised to see Sankey Diagrams make their way into modern data visualization tools such as Tableau or QlikView, perhaps even into Excel some day…”. This is of course an idea I like…
