    What are Sankey diagrams?

    Sankey diagrams are a specific type of flow diagram. They are used to visualize material streams or energy flows.

    They are used, for example, in energy management, facility management, chemical or process engineering. Sankey diagrams are a good alternative to bar charts or pie charts, if you wish to show flow quantities.

    In Sankey diagrams the width of the arrows are proportional to the flow quantity it represents. So, attention is drawn immediately to the most important flows in the process system.

    Who is Mr. Sankey?

    Sankey diagrams are named after Captain Matthew Henry Phineas Riall Sankey, an Irish engineer, who was working on energy efficiency of steam engines. He published the first energy flow diagram of this kind in 1898.
