A Sankey chart is a visualization tool that shows the flow of data between different stages.
It is often used to show how different inputs contribute to an output, and to demonstrate the potential for losses at each stage.
Sankey charts consist of a set of boxes or nodes that represent different stages in a process and a set of arrows that show the flow of data between these stages.
The width of each arrow is proportional to the amount of data flowing through it, so it is easy to see the relative contribution of each input to the output.
Sankey charts can be used in many different fields, including finance, logistics, and energy.
