Talk:Sankey diagram

Comment
The following comment ("...apparently lifted...") from 2007 doesn't seem to apply now in 2017. (The website referenced is now merely http://www.sdraw.com and its starting page seems to have no text that resembles the wikipedia article.)... Mroam (talk) 16:21, 7 March 2017 (UTC)

This text is this article was apparently lifted, verbatim, from  http://www.sdraw.com/en/index.html    It really looks as if this was just copied & pasted from a commercial website. The article is too short, I agree, but it should not be expanded with marketing phrases. I suggest to delete the last paragraph in the Software section. Shangri67 12:40, 27 January 2007 (UTC)

What is the utility of this diagram in chemical engineering? chandan chattopadhyay
 * Mostly Sankey diagrams are able to give you a good overview of a system, which is a good thing to have e.g. in optimisation. Sankey diagrams are very versatile and you can depict the flow of any kinds of conservative parameter through a system. One could for instance make a diagram of a reactor cascade showing the losses of raw material input in the sequence, even including internal recycling. Or the flow of energy (including "inputs" from exothermal reactions and "losses" to endothermal reactions). 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 April 2011 (UTC)

Minard's Sankey map predates Sankey
"Sankey diagrams are name after Irish Captain Matthew Henry Phineas Riall Sankey, who is considered to have been the first to use this type of diagram in 1898 in a publication on the energy efficiency of a steam engine (see reproduction in[1], page 8)."

Of course, the way it is punctuated, this is a probably true statement--I'm guessing that nobody else used this type of diagram in a publication on the energy efficiency of a steam engine (during that year). But the concept predates Sankey, as demonstrated by Minard's famous diagram of Napoleon's army attrition. Is there some source that says why Sankey gets credit? Is it because Sankey's was abstract?

illustration missing/replaced
The text claims "the illustration" depicts energy flow in a factory. The two illustrations near the paragraph both describe a steam engine.

new external link looks like an ad
The following was just pasted onto the end of the existing "External Link". My instinct was to "revert", but I thought I would solicit a second opinion.
