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:

A computer simulation (or "sim") is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied to see how the system works. By changing variables in the simulation, predictions may be made about the behaviour of the system. It is a tool to virtually investigate the behaviour of the system under study. [3]
A spaghetti plot (also known as a spaghetti chart, spaghetti diagram, or spaghetti model) is a method of viewing data to visualize possible flows through systems. Flows depicted in this manner appear like noodles , hence the coining of this term. [ 1 ]
Prostista taxonomy vs. phylogeny - This diagram shows the phylogeny of eukaryotes based on some recent analyses superimposed over the current kingdom and subkingdom-level taxonomy of protists. The purpose of the image is to demonstrate the paraphyly of most protist groupings, particularly those belonging to kingdom Protozoa: subkingdom Eozoa.
