Sankey charts are a powerful and visually appealing way to represent the flow of data and make decisions about the future. They were invented by Japanese engineer Akira Sankey in the 1930s and have since become a popular tool in fields such as finance, logistics, and sustainability.

One of the main advantages of Sankey charts is their ability to show the relative importance of different sources and destinations for a particular flow of data. This makes them ideal for identifying areas where resources are being overused or underused, and for exploring ways to optimize the flow of goods, services, or information.

To create a Sankey chart, you need to specify the inputs and outputs of your flow, as well as the relative quantities or values of each. The chart can then be customized to show the relationships between these data points, using a range of visual techniques such as arrows, labels, and color coding.

One of the most powerful applications of Sankey charts is their ability to visualize the circular economy. This is the idea that products should be designed to be recycled or reused, rather than becoming wasteful byproducts of the production and consumption process. By showing the flow of materials and resources through the economy, Sankey charts can help identify opportunities to reduce waste and increase efficiency.

For example, a Sankey chart for the production of a particular product might highlight the input of raw materials, such as plastic or metal, and the output of finished products. By examining the flow of these materials, it might be possible to identify areas where resources are being overused or underused, and to explore ways to optimize the production process to reduce waste.

Another application of Sankey charts is in the field of finance. By visualizing the flow of assets and liabilities between different parties or organizations, Sankey charts can help identify areas where risk or uncertainty exists, and allow stakeholders to make informed decisions about the future.

For example, a Sankey chart for the flow of funds in a particular industry might highlight areas where there are excess funds, and where these funds might be invested to maximize returns or create positive social or economic impacts.

Overall, Sankey charts are a powerful and flexible tool for visualizing change and making decisions about the future. They offer a wealth of insights into the flow of data and resources, and can be applied to a wide range of fields and industries. With the right data and visualization techniques, Sankey charts can help unlock the full potential of these flows, and contribute to a more sustainable, efficient, and equitable future.
