Sankey charts are a type of flowchart that are particularly useful for visualizing complex systems and relationships. They are named after their creator, George Sankey, an engineer who developed the chart in the 1920s to help with the design of chemical reactors. Since then, Sankey charts have been used in a wide range of fields, including chemistry, engineering, economics, and ecology.

One of the key advantages of Sankey charts is their ability to represent both directed and circular flow. This makes them particularly useful for visualizing processes that involve both inputs and outputs, as well as feedback loops. For example, a Sankey chart could be used to visualize the flow of materials through a manufacturing process, highlighting which steps consume raw materials and which steps produce finished products.

Another advantage of Sankey charts is their ability to represent hierarchical relationships between different processes or entities. For example, a Sankey chart could be used to visualize the flow of funds through a financial system, highlighting which types of investments generate income and which types of investments consume income.

Sankey charts can also be customized to show different types of flow or transformation. For example, you can use different colors or symbols to represent different types of inputs or outputs, or different types of transformations or conversions. This makes it easy to identify patterns or trends in the data being visualized.

To create a Sankey chart, you will need a tool that is able to generate flowcharts and diagrams. There are many software programs available that can do this, including Microsoft Visio, Lucidchart, and DrawFlow. These programs allow you to drag and drop shapes and connectors to create your chart, and typically have a range of customization options available for fonts, colors, and other visual elements.

Once you have created your Sankey chart, you can use it to gain insights and understanding into complex systems and relationships. By examining the flow of inputs and outputs, hierarchical relationships, and transformations, you can identify bottlenecks or inefficiencies in the system being visualized, as well as opportunities for improvement or optimization.

In conclusion, Sankey charts are a powerful tool for visualizing complex systems and relationships. They allow us to represent both directed and circular flow, as well as hierarchical relationships between different processes or entities. By customizing these charts to show different types of flow or transformation, we can gain insights into patterns or trends in the data being visualized. Whether you are an engineer designing chemical reactors or an ecologist studying nutrient cycles in a ecosystem, Sankey charts are an invaluable tool for understanding the dynamics of complex systems.
