Sankey charts are an excellent way to visualize the flow of materials, energy, or information between different entities or stages in a process. Created using the Sankey Diagram software package, these charts are highly flexible and can be used in a wide range of applications. In this article, we will explore the basics of Sankey chart creation, as well as some of the most creative ways to use them.

What is a Sankey Chart?

Sankey charts are a type of flowchart that allows you to graphically represent the flow of materials, energy, or information through a series of steps or entities. Named after physicist Kenneth Maclaine Sankey, these charts are widely used in engineering, chemistry, and other fields where process optimization is critical.

Sankey charts are particularly useful for visualizing the flow of materials or energy between different stages in a process. For example, a Sankey chart could be used to represent the flow of raw materials through an assembly line, or the movement of energy from a power plant to end-use consumers.

How to Create a Sankey Chart

Creating a Sankey chart is straightforward with the help of the Sankey Diagram software package. To get started, follow these steps:

1. Download and install the Sankey Diagram software package from the official website.
2. Launch the software and select “New Diagram”.
3. Enter the names and descriptions of the entities or stages in your process.
4. Create the relationships between the entities using arrows and connectors. You can customize the appearance of arrows and connectors to match your preferences.
5. Optionally, you can add nodes or steps to the chart if needed.
6. Customize the chart appearance and formatting, such as colors, fonts, and line styles.
7. Generate the Sankey chart and save it to your desired location.

Applications of Sankey Charts

Sankey charts are an ideal visualization tool for a wide range of applications, including:

1. Process modeling and optimization: Sankey charts can be used to visualize the flow of materials or energy through a process, making it easier to identify areas for improvement.
2. Heat transfer and energy analysis: Sankey charts can be used to represent the flow of heat or energy through a system, helping engineers to optimize the performance of their designs.
3. Supply chain management: Sankey charts can be used to visualize the flow of materials or information through a supply chain, making it easier to track inventory and identify areas for improvement.
4. Environmental analysis: Sankey charts can be used to represent the flow of materials or pollutants through an environmental system, helping analysts to identify sources of pollution and develop effective solutions.
5. Financial analysis: Sankey charts can be used to represent the flow of funds or assets through a financial system, making it easier to identify areas for growth or cost reduction.

Conclusion

Sankey charts are a powerful visualization tool for understanding and optimizing the flow of materials, energy, or information through a process. With their ability to represent complex systems and relationships, they offer a wealth of insights for engineers, analysts, and practitioners in a wide range of fields. Whether you are designing a new product, optimizing a production process, or analyzing an environmental or financial system, Sankey charts can help you make informed decisions and achieve your goals.
