In today’s digital age, data is the key to unlocking knowledge and making sense of the world around us. One way to effectively visualize and analyze large amounts of data is through the use of Sankey charts. In this article, we will take a closer look at what Sankey charts are, how they work, and how they can be used to map the flow of information.
What is a Sankey Chart?
Sankey charts are a type of diagram that uses flow lines to illustrate the direction and magnitude of a flow or exchange of information. These charts are commonly used to portray information flows between different entities, such as people, organizations, or industries. By following the flow lines, viewers can easily interpret the information and quickly identify key trends and patterns.
The basic components of a Sankey chart include:

• A series of “nodes” or items that represent the entities being discussed.
• Line segments that represent the flow between these nodes.
• A legend that describes the meaning and interpretation of the flow line.

How Sankey Charts Work
Sankey charts work by showing the direction and magnitude of a flow through a series of nodes. Each node is labeled with information or data that is relevant to the flow at that point. The line segments connecting each node represent the direction and magnitude of the flow, with the flow lines being assigned a color to emphasize the importance of the flow.
To create a Sankey chart, you will need to gather the necessary data and gather information about the entities or items that are being discussed. After that, you can use this information to create a Sankey chart that effectively portrays the flow of information.
Applications of Sankey Charts
Sankey charts are widely used in fields such as economics, management, and social sciences to analyze and visualize flow and exchange of information. Here are some of the applications of Sankey charts:

• In economics, Sankey charts can be used to illustrate the supply and demand curves for a given product or service, and to analyze the flow of transactions between buyers and sellers.
• In management, Sankey charts can be used to illustrate the flow of information between different departments or teams within an organization.
• In social sciences, Sankey charts can be used to analyze the flow of information between different groups or communities.

Conclusion
Sankey charts are a powerful tool for mapping the flow of information. By following the flow lines and interpreting the information, viewers can quickly understand the direction and magnitude of a flow. Whether you are analyzing supply and demand, reviewing a supply chain, or studying the flow of information between different groups, Sankey charts are a useful and effective way to visualize and communicate complex information.
