e!Sankey - a software tool to easily create Sankey diagrams. A Sankey diagram is a directional flow chart where the magnitude of the arrows is proportional to the quantity of flow. Sankey diagrams are a useful way of visualizing material flows energy efficiency or costs. If you are a chemical engineer an environmental engineer or process engineer a professional in quality management logistics or finance you can use e!Sankey diagrams to display flow quantities in a production system. Numerous display and scaling options help you get the best Sankey diagrams for your presentation.e!Sankey makes drawing Sankey flow diagrams really easy.
