Sankey charts are a type of flowchart that are often used to visualize data flow and transitions between different entities or stages. They are named after their creator, Louis Sankey, an English statistician who developed the chart in the late 19th century. Sankey charts are particularly useful for analyzing and understanding complex systems where there are multiple interconnected components, such as supply chains, financial transactions, or information flows.

One of the strengths of Sankey charts is their ability to show both the direction and magnitude of flow between different entities. This allows viewers to quickly understand which entities are the primary sources or receivers of a particular resource or information. Sankey charts can also be easily adapted to show different types of transitions, such as causal relationships or probabilistic distributions.

To create a Sankey chart, you will need to gather data on the flow of resources or information between different entities. This data should be presented in a tables format with two columns for the source and the destination. Each row in the table represents a flow of a certain resource from one entity to another.

Once you have gathered your data, you can use a spreadsheet program such as Microsoft Excel or Google Sheets to create the chart. One of the advantages of using a spreadsheet program is that you can easily adjust the chart to show different types of transitions or add additional information such as axis labels or flow lines.

Sankey charts are useful for a wide range of applications, from understanding the flow of goods in a supply chain to visualizing the flow of information in a social media network. They are an effective tool for identifying bottlenecks and areas for improvement in a system, and can also be used to illustrate the overall structure of a complex system.

In conclusion, Sankey charts are a powerful visualization tool for understanding complex systems where there is data flow and multiple transitions between different entities. By presenting the flow of resources or information in a clear and concise way, Sankey charts enable viewers to quickly understand the dynamics of a system and identify areas for improvement. Whether you are analyzing a supply chain, a financial transaction, or an information flow, Sankey charts can help you to better understand and improve your system.
