Sankey charts are a powerful tool for visualizing data flow and transformation. They are particularly useful for showing the direction, magnitude, and purpose of a flow of goods, services, or information. In this article, we will discuss how to create Sankey charts and some of the various applications of this type of chart.

What are Sankey Charts?

Sankey charts are a type of flowchart that use arrows to represent the movement of goods, services, or information from one place to another. The chart is named after the Irish physicist and chemist, Peter Sankey, who first introduced the concept in the 1920s. Sankey charts are particularly useful for showing the direction and purpose of a flow, as well as the magnitude of the flow.

Creating a Sankey Chart

Sankey charts can be created using a variety of software programs, such as Microsoft Visio, Lucidchart, or draw.io. You can also create a Sankey chart using spreadsheet software, such as Excel.

To create a Sankey chart, follow these steps:

1. Start with a blank page or document.
2. Insert a flowchart template, such as a Sankey chart template, into the document.
3. Customize the template as needed to represent your data.
4. Connect the flowchart components using arrows to show the direction and purpose of the flow.
5. Add labels and other decorative elements as desired.
6. Make any necessary adjustments to the chart to ensure it accurately represents your data.

Applications of Sankey Charts

Sankey charts are useful in a wide variety of industries and applications. Some examples include:

1. Supply chain management: Sankey charts are useful for showing the flow of goods from suppliers to customers, highlighting any bottlenecks or inefficiencies in the supply chain.
2. Financial analysis: Sankey charts can be used to show the flow of funds, such as the movement of money between different accounts or investments.
