Sankey charts are a type of flowchart that allow you to easily visualize the flow and circulation of data. They are particularly useful for showing the direction and magnitude of flow between different data points or entities. In this article, we will explore how to create Sankey charts and the many applications for this powerful visualization tool.

The Sankey chart was originally developed by Raymond A. Yale, an MIT researcher, in the 1930s. It is named after his son, John Yale Sankey, who later worked with his father to refine the chart. Over the years, the chart has become a popular tool for data visualization, especially in fields such as operations research, transportation, and economic analysis.

Creating a Sankey chart is relatively easy, and there are several software tools that support the creation of Sankey charts. Some common tools include Microsoft Excel, Visio, Lucidchart, and SmartDraw. Here’s how to create a Sankey chart in Microsoft Excel:

1. Open Microsoft Excel and create a new spreadsheet.
2. Insert a new chart by navigating to the Insert tab in the ribbon and selecting Chart.
3. From the Chart library, select Sankey chart.
4. Customize the chart design by adjusting the colors, shapes, and labels as desired.
5. Drag and drop data series into the chart to create the flow of data.
6. Save and format the chart as needed.

Once you have created your Sankey chart, you can use it to visualize flow and circulation in your data. Some common applications include:

1. Analyzing data flow in a supply chain to identify bottlenecks and inefficiencies.
2. Visualizing the flow of money or resources in a financial system or economy.
3. Analyzing the diffusion of ideas or opinions over time.
4. Identifying patterns and trends in data over time.

Sankey charts are a powerful visualization tool for understanding the flow and circulation of data. They are especially useful for large, complex datasets, which can be difficult to visualize using other types of charts. With their clear and直观 flow diagrams, Sankey charts provide a simple and effective way to understand the relationships between different data points or entities. Whether you are analyzing supply chains, financial systems, or the diffusion of ideas, Sankey charts can help you unlock the power of your data.
