Minard's diagram of Napoleon's invasion of Russia, using the feature now named after Sankey. One of the most famous Sankey diagrams is Charles Minard's Map of Napoleon's Russian Campaign of 1812. [5] It is a flow map, overlaying a Sankey diagram onto a geographical map. It was created in 1869, predating Sankey's first Sankey diagram of 1898.
Other programming options include an embedded Python environment, and an R Console plus support for Rserve. Origin can be also used as a COM server for programs which may be written in Visual Basic .NET, C#, LabVIEW, etc. Older (.OPJ), but not newer (.OPJU), Origin project files can be read by the open-source LabPlot or SciDAVis software.
These diagrams depict elements as points in the plane, and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. The points inside a curve labelled S represent elements of the set S, while points outside the boundary represent elements not in the set S.
But Dash also works for R, and most recently supports Julia, and while still described a Python framework, Python isn't used for the other languages, "describing Dash as a Python framework misses a key feature of its design: the Python side (the back end/server) of Dash was built to be lightweight and stateless [allowing] multiple back-end ...
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:
[1] d'Ocagne sought a way to provide graphical calculation of mathematical functions using alignment diagrams called nomograms which used parallel axes with different scales. For example, a three-variable equation could be solved using three parallel axes, marking known values on their scales, then drawing a line between them, with an unknown ...

Whether or not a Sankey diagram is a sensible thing really depends on what you want to be able to show with the diagram. It is not a "standard diagram" used in only one particular way; creativity is allowed :-) Although one absolute rule: width of fluxes must be proportional to the depicted flow magnitude -- 62.202.111.50 ( talk ) 12:37, 19 ...
