Sankey Chart
A Sankey chart is a type of data visualization that displays the flow of data between different categories or stages in a process. It consists of a series of nodes that represent the categories or stages, connected by links or flows that represent the movement of data between them. The width of each flow corresponds to the amount or volume of data being transferred.
Sankey charts are useful for visualizing complex data sets with many categories or stages, and for understanding the relationships and dependencies between them. They are often used to visualize energy flows, material flows, or financial flows, but can be applied to any type of data where the movement between categories or stages is important.
