Sankey charts are widely used in various fields such as engineering, economics, and social sciences. They are capable of conveying complex financial or network data with clarity and ease, and they can be used to visualize a wide range of data and phenomena.

Before diving into the specifics of how to create and use a Sankey chart, it is important to understand what it is and how it functions. Sankey charts have a small node that represents the source or node and a larger node that represents the sink or destination. Each segment connecting a source to a sink also has a value corresponding to the amount of data flowing through it. The thickness of the segment indicates the amount of data flowing out of the source and into the sink.

For example, consider the flow of water through a reservoir:

Source: Rainwater
Sink: Tank
| |
| 500 |
| 200 |
| 100 |
| 50 |
| 10 |
Sink: Water
Source: Tank

In this example, there are multiple segments connecting the source and sink. The amount of water entering and leaving the reservoir can be represented by the amount of water through each segment, and the thickness of the segments can be used to show the direction of the flow.

There are several tools and platforms where you can create Sankey charts online. Some popular ones include:

• Canva: A graphic design platform that offers pre-built templates and tools to create Sankey charts.
• Microsoft Visio: A diagramming tool that can be used to create Sankey charts and other types of network diagrams.
• Lucidchart: A diagramming and diagram management software that offers a variety of options for creating and modifying Sankey charts.

Once you have created a Sankey chart, you can use it to visualize a variety of data and phenomena. For example, if you are working with economic data, you can use a Sankey chart to visualize the flow of money through an economy from the sources (jobs, exports, imports) to the sinks (consumer, business investment). Alternatively, you can use a Sankey chart to visualize the flow of resources through a project or a network.

Overall, Sankey charts are a powerful tool for visualizing complex data and phenomena. With their ability to convey information clearly and effectively, they can be an invaluable asset for anyone working with large amounts of data.
