Sankey charts are a powerful data visualization tool that can be used to visualize the flow of data between different categories or entities. They are especially useful for showing the relationships and dependencies between different items, and can be used to represent everything from the flow of goods and services to the movement of ideas or information.

In this article, we will explore the basics of Sankey chart creation and some of the many applications for this type of chart.

What is a Sankey Chart?

A Sankey chart is a type of flowchart that is used to represent the flow of data between different categories or entities. It is named after its creator, Jiro Sankey, a data visualization expert who developed the chart in the 1970s.

The chart consists of a set of interconnected circles, represented by nodes, that represent different categories or entities. The connections between the nodes represent the flow of data between them, with the direction of the flow indicated by arrows.

The unique aspect of Sankey charts is that they are able to show the relative weights or amounts of data flowing between different nodes. This is achieved by using different colors or patterns to represent the different amounts of data flowing between the nodes.
