Sankey charts are a popular tool in visualizing complex data flows that can be used to compare and contrast different variables or categories. Sankey charts are a type of network diagram that use a series of arcs connecting nodes to show the flow of data or information through a system. Below, we’ll take a closer look at how you can create a sankey chart and some of the applications it can be used for.
Basics of Sankey Charts
A straight line that runs from one node to another is called a “link,” and the area between the link and the nodes at the ends of the link is called the “arc.” In this diagram, the sankey chart shows how the number of students attending each college in the United States changed over time. The arc represents the number of students attending a given college, and the link shows the correlation between the number of students attending a given college and the number of students attending another college.
Types of Sankey Chart Create a Sankey chart using the basic steps outlined below.

1. Choose the data for the chart. You’ll need to have access to the data you want to visualize.
2. Create the chart. Use a software program to create the chart. There are multiple software options available, such as Microsoft Excel, Google Drawings, and Tableau.
3. Format the chart. Customize the appearance of the chart by adjusting the colors, labels, and other elements.
4. Customize the chart data. You can add or remove nodes or links to fine-tune the chart.
5. Add labels and annotations to the chart. This can help to provide context for the information being presented.

Sankey Charts Use the data to show how the information flows through a system
Sankey charts are useful for showing the flow of information or data through a system. They can be used to show the relationships between variables or categories and their interactions with each other. For example, you can use a sankey chart to show how different types of energy are distributed in a system, or how different types of waste are generated in a system.
Applications of Sankey Charts
Sankey charts can be used in a variety of fields, including economics, social sciences, and environmental science. They can be used to:

• Visualize the flow of information or data through a system.
• Show relationships between variables or categories.
• Identify problem areas or areas with potential for improvement.
• Provide a way to compare different variables or categories.
• Describe the system or process being studied.
• Identify connections between different systems or processes.

Conclusion
Sankey charts are a versatile tool for visualizing complex data flows. By following these basic steps, you can create a sankey chart that shows the flow of information or data through a system. With the right data and a well-designed chart, you can clearly and effectively communicate the information being presented.
Sankey charts are a useful tool for anyone who needs to understand the flow of information or data, particularly in fields like economics, social sciences, and environmental science. With a bit of creativity and ingenuity, you can use sankey charts to make complex information more accessible and understandable.
