1. What is a Sankey chart?

A Sankey chart is used to depict flows and their quantities in proportion to others. It contains nodes connected by lines, and the width of lines depends on the number of flows from source to destination, so the bigger the quantity, the wider the line.

When to use Sankey chart?

A Sankey chart is typically used to visualize the flow or distribution of data, especially when there is a need to demonstrate the transition or movement of quantities between different categories or stages. It is particularly useful when showcasing the relationship, proportion, or progression of data through a series of interconnected nodes or pathways.
