Sankey charts, also known as directed flow charts, are a powerful visualization tool for understanding and optimizing data flow. They are particularly useful for showing the flow of materials, money, or information through a system, and can be used to identify bottlenecks and areas for improvement. In this article, we will explore how to create Sankey charts and the wide range of applications for this type of visualization.

How to Create a Sankey Chart

A Sankey chart is created using specialized software, such as Visio or PowerPoint, or online tools like Sankey.org. The process of creating a Sankey chart involves several steps:

1. Identify the nodes: In a Sankey chart, each node represents a source or sink of data or material. The flow of data or material between nodes is represented by directed lines.
2. Draw the directed lines: Starting at the source node, draw a directed line to each sink node, representing the flow of data or material.
3. Assign directions: Indicate the direction of flow by drawing arrows on the directed lines.
4. Add labels: Label each node and each directed line with relevant information, such as the type of data or material flowing and the quantity or value of the flow.

Applications of Sankey Charts

Sankey charts are a flexible and powerful visualization tool that can be used in a wide range of applications, including:

1. Material Flow: Sankey charts can be used to visualize the flow of materials through a production process or supply chain. They can help identify bottlenecks and inefficiencies in the flow of materials, such as excess inventory or unnecessary transportation.
2. Financial Flow: Sankey charts can be used to visualize the flow of money through a financial system, such as a company’s accounts or a government’s budget. They can help identify areas where money is being wasted or flowing unnecessarily.
3. Information Flow: Sankey charts can be used to visualize the flow of information through a company or organization. They can help identify bottlenecks or areas where information is not flowing effectively, such as a lack of communication or poorly designed policies.
4. Performance Optimization: Sankey charts can be used to visualize the flow of resources or human capital through a system, such as a sports team or a military unit. They can help identify areas where resources are being underused or overused, and can be used to optimize the flow of resources to achieve better performance.

Conclusion

Sankey charts are a powerful visualization tool for understanding and optimizing data flow, particularly for applications related to materials, money, or information. By creating a Sankey chart, you can gain a clear and concise view of the flow of data or material through a system, and identify areas for improvement. With the right software or online tools, creating a Sankey chart is simple and easy, and the benefits of this type of visualization can be substantial.
