Example of a Sankey diagram Sankey's original 1898 diagram showing energy efficiency of a steam engine. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property.
Sankey's diagram, 1898. In an 1898 article about the energy efficiency of a steam engine in the Minutes of Proceedings of the Institution of Civil Engineers Sankey introduced the first energy flow diagram: a visualisation to be christened Sankey diagram. [4] Sankey gave the following explanation how to read the image:
Visual tools used in information visualization include maps for location based data; hierarchical [7] organisations of data such as tree maps, radial_trees, and other tree_structures; displays that prioritise relationships (Heer et al. 2010) such as Sankey diagrams, network diagrams, venn diagrams, mind maps, semantic networks, entity ...

An example of such a diagram is the illustration of the flows in a nuclear submarine propulsion system, which shows different streams back and forth in the system. The representation of such a system can be supplemented by one or more flowcharts, which show the sequence of one of the flows in one direction, or any of the control flows to manage ...

Flow visualization is the art of making flow patterns visible. Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to the naked eye without methods to make them this visible.
This type of band graph for illustration of flows was later called a Sankey diagram, although Matthew Henry Phineas Riall Sankey used this visualisation 30 years later and only for thematic energy flow. Charles Minard's map of Napoleon's disastrous Russian campaign of 1812.
