What is a Sankey diagram simple?

Summary. Sankey diagrams are a specific type of flow diagram used for visualization of material, cost or energy flows. They show energy or mass flows with arrows proportional to the flow quantity. They have directed arrows (between at least two nodes) featuring flows in a process, production system or supply chain.
