Sample diagram and its defining datasheet
Sankey diagrams are suitable for representing the energy or mass flows though a system. They were invented by the irish engineer M. H. P. R. Sankey (* 1853, + 1921) and were mainly used for energy flows in power plants.
The example below shows the fate of the energy in fissalbe uranium for nuclear electricity production.

Easy, isn't it?
