Sankey charts, also known as flow charts, are a powerful visualization tool used to represent the flow of materials, energy, or information. They are particularly useful in understanding the circular flow of resources in a system, and identifying opportunities for optimization or recovery.
Sankey charts are named after William Sankey, an American mathematician and statistician who developed the chart in the early 20th century. He used the chart to study the flow of electrical energy in power systems, and later, it was applied to other fields such as ecology, economics, and engineering.
Here are some steps to create a Sankey chart:
- Identify the flow of interest: Determine the materials, energy, or information that you want to visualize the flow of.
- Define the starting and ending points: Identify the source of the flow and the destination.
- Assign flow values: Determine the amount or rate of flow of each element through the system.
- Draw the chart: Use a piece of paper or software to draw the chart, starting with the source and ending with the destination. Divide the chart into segments for each flow value, and label them so that you can easily track the flow.
- Customize the chart: You can customize the chart by adding additional information, such as the name of each element, or by highlighting specific segments to draw attention to.
Sankey charts are a flexible visualization tool that can be applied to many different systems. They can help you identify瓶颈、优化流程、提高资源利用率，甚至可以帮助你了解生态系统的循环过程。
For example, a Sankey chart could be used to visualize the flow of materials through a recycling center. By tracking the flow of materials in and out of the center, the chart could help identify areas where materials could be diverted away from landfills or wasted, and where resources could be retrieved for reuse.
Another example of a Sankey chart application is in the field of energy management. By visualizing the flow of energy through a power grid, a Sankey chart could help identify areas where energy could be lost or wasted, and where energy-efficient upgrades could be made to reduce energy costs and improve sustainability.
Overall, Sankey charts are a useful visualization tool that can help you understand and optimize the flow of materials, energy, or information in any system. By creating a Sankey chart, you can gain valuable insights into the circulatory processes of your system and take steps to improve efficiency and sustainability.
