Sankey charts, also known as flowcharts, are a type of diagram used to visualize data flow and efficiency. They were invented by Charles Sankey in the late 19th century and have since become a popular tool for data visualization and analysis.

One of the main benefits of using a Sankey chart is that it allows you to quickly and easily see the flow of data through a system or process. This is particularly useful when trying to understand complex systems or processes, as it can be difficult to see the underlying data flow.

Another advantage of using a Sankey chart is that it allows you to easily see where in the process data is being transformed or filtered. This can be particularly helpful when trying to optimize a process by identifying areas where improvements can be made.

To create a Sankey chart, you will need to gather data that describes the flow of data through a process or system. This could be data on the inputs and outputs of a process, or data on the steps involved in a process. Once you have this data, you can use a software tool such as Microsoft Visio or Lucidchart to create your chart.

One common use of Sankey charts is in process mapping. This involves creating a visual representation of the steps involved in a process, and identifying areas where improvements can be made. By using a Sankey chart, you can easily see the flow of data through the process and identify areas where data is being transformed or filtered.

Another application of Sankey charts is in supply chain management. By visualizing the flow of data through a supply chain, you can quickly and easily see where in the process data is being transformed or filtered. This can be particularly helpful when trying to optimize a supply chain by identifying areas where improvements can be made.

In conclusion, Sankey charts are a powerful tool for visualizing data flow and efficiency. They allow you to quickly and easily see the flow of data through a process or system, and identify areas where improvements can be made. Whether you are trying to understand a complex system or process, or trying to optimize a supply chain, a Sankey chart can be a valuable tool.
