Sankey charts are a type of flowchart that are used to represent the flow of materials, information, or energy. They are particularly useful for visualizing the relationships and dependencies between different elements in a system. In this guide, we will explore how to create Sankey charts and the various applications of this type of chart.

What is a Sankey Chart?
Sankey charts are a type of flowchart that use directed arrows to represent the flow of materials, information, or energy. The arrows are labeled with specific amounts or rates of flow, and the chart shows the direction and magnitude of the flow. Sankey charts are particularly useful for visualizing the relationships and dependencies between different elements in a system.

Components of a Sankey Chart
Sankey charts consist of several components, including:

1. Directed Arrows: The arrows in a Sankey chart represent the flow of materials, information, or energy.
2. Labeled Arrows: Each arrow in the chart is labeled with a specific amount or rate of flow.
3. Network: The network component of a Sankey chart represents the flow relationships between different elements in the system.

Creating a Sankey Chart
There are several software tools available for creating Sankey charts, including Microsoft Excel, Lucidchart, and SmartDraw. Each of these tools has its own set of features and capabilities. Here are the general steps for creating a Sankey chart:

1. Determine the source and sink of the flow.
2. Identify the flow patterns and their rates.
3. Draw the arrows in the chart to represent the flow.
4. Label the arrows with the flow rates.
5. Create the network component of the chart to show the flow relationships between different elements.

Applications of Sankey Charts
Sankey charts are a useful visual tool for identifying and optimizing the flow of materials, information, or energy in a system. Some common applications of Sankey charts include:

1. Process Analysis: Sankey charts can be used to analyze and improve a process by visualizing the flow of materials, information, or energy and identifying areas for improvement.
2. Supply Chain Management: Sankey charts can be used to manage and optimize a supply chain by visualizing the flow of goods, services, or information and identifying potential bottlenecks.
3. Environmental Impact Assessment: Sankey charts can be used to visualize the flow of materials, energy, or waste in an ecosystem and identify areas for improvement in terms of resource conservation and sustainability.

Conclusion
Sankey charts are a powerful tool for visualizing the flow of materials, information, or energy in a system. They are particularly useful for identifying and optimizing the flow of resources in a process, supply chain, or environmental system. With the right software tools and a willingness to analyze and improve, Sankey charts can help anyone master the flow of information and make a positive impact.
