Sankey charts are a powerful visualization tool that can help you understand the flow and relationships of data. They are often used to show the direction and magnitude of dependencies between different variables or entities. In this article, we will explore how to create Sankey charts and the various ways they can be used to analyze and visualize data.

What are Sankey charts?

Sankey charts are a type of flowchart that use directed arrows to represent the flow of data between different nodes or entities. Each node represents a variable or entity, and the directed arrows indicate the direction of the flow. The arrows are weighted to show the magnitude of the flow, with the weights summing to 1.

Sankey charts are particularly useful for visualizing complex data sets where multiple dependencies exist between different variables or entities. They can help you identify patterns and relationships that might not be immediately obvious from a traditional flowchart or bar chart.

How to create Sankey charts

Creating a Sankey chart involves selecting the data you want to visualize and designing the chart to show the desired flow and relationships. There are several software programs that can be used to create Sankey charts, including Microsoft Excel, LibreOffice Calc, and Visio.

To create a Sankey chart in Excel, follow these steps:

1. Enter your data into a table with one column for the source and one column for the destination.
