Sankey charts are a type of flowchart that are used to visualize and analyze the flow of materials, information, or resources between different nodes or entities. They are named after their creator,丰田喜一郎（Hirotaka Sankey），他在20世纪30年代发明了这种图表。
Sankey charts consist of a set of interconnected circles, each representing a node or entity in the system. The circles are connected by arrows that represent the flow of materials, information, or resources between them. The length of the arrows can be used to represent the amount or rate of flow.
One unique feature of Sankey charts is that they can be used to visualize both directional and non-directional flows. This makes them ideal for analyzing complex systems where multiple processes or pathways exist. Additionally, they can be easily modified to show different levels of detail and can be customized to include additional information such as costs or timelines.
Applications for Sankey charts include process mapping and optimization, resource management, supply chain analysis, and environmental impact assessment. For example, a company may use a Sankey chart to identify areas where improvements could be made to optimize their supply chain operations and reduce waste. Alternatively, an environmental organization may use a Sankey chart to study the movement of pollutants through a water system in order to identify areas for cleanup efforts.
