Sankey charts are a type of flow chart that are particularly useful for visualizing data flow and performance within a system. They were originally developed by George Odifreddi in the early 1980s as a way of analyzing the flow of energy between different parts of a system. Since then, they have been widely used to visualize a variety of data flows, including information, goods, and services.

To create a Sankey chart, you will need to gather data on the inputs and outputs of your system, as well as the flow rates between those inputs and outputs. This data can be presented in a variety of ways, including in a table or a spreadsheet.

Once you have your data, you can use a Sankey charting tool to create a visual representation of it. There are many tools available that can help you create Sankey charts, including free software packages such as SankeyJS and Gephi, as well as commercial charting tools such as Microsoft Visio and Lucidchart.

When creating a Sankey chart, there are a few key considerations to keep in mind. First, it is important to choose the right type of chart to represent your data. If the flow of your system is highly influenced by one or a few inputs or outputs, you may want to consider using a directed acyclic graph (DAG) instead of a Sankey chart. Second, it is important to choose the right colors and symbols to represent your data. Bright colors and clear icons can help make your chart easier to understand and interpret.

Sankey charts are a powerful visualization tool for understanding data flow and performance within a system. By using a Sankey chart, you can easily see how inputs and outputs are connected and how data flows between them. This can be particularly useful for identifying bottlenecks, optimizing processes, and improving the overall performance of your system.
