Sankey diagrams have been widely used in various fields, but their impact is most widely recognized in the area of applied mathematics and analytics. The Sankey diagram is a type of flow diagram in which energy or information flows through structures, such as pipes or channels, and their relationship is determined graphically using shapes and symbols instead of arrows. It has been used to represent the flow of resources, information, or data, as well as the flow of energy in complex systems. Here are some intriguing facts about the Sankey chart and its applications.

One of the most fascinating aspects of Sankey charts is its ability to visually represent the flow of information or resources. For example, in the United States, the Sankey chart has been used to track the number of natural disasters, such as hurricanes and wildfires. The chart is filled with the shape of each structure that represents the flow of information, such as roads, rivers, and pipes. This enables the viewer to understand the flow of information in the disaster-stricken area and find out how the natural disaster has affected the various sectors of the economy.

Another fascinating aspect of this diagram is its ability to capture complex relationships between different structures. For example, the Sankey Chart represents the communication between networks of different countries. Each country is marked with different colors to represent different networks, and each network is represented by a flow of information. The diagram helps us identify which countries are in contact with other countries, and how one country can affect another.

In addition, the Sankey chart can be used to track the flow of data in different organizations or industries. For example, a company can create a Sankey chart for its supply chain, and the chart can represent the flow of materials, labor, and other resources. The chart can also help identify weak points in the supply chain, such as slow-moving materials, which can be addressed through improved logistics.

The Sankey chart has also been used in social sciences. In 2014, researchers used a Sankey diagram of mental health to show the flow of mental health services in different regions. They found that access to mental health care is uneven in different parts of the United States and that areas with fewer resources had fewer providers. This helped the researchers identify areas that needed more mental health resources.

In conclusion, Sankey diagrams have played a significant role in the field of applied mathematics and analytics, and have been used to represent the flow of information or resources in complex systems. They enable the analysis of different sectors and their impact on the economy. Whether you are tracking the flow of natural disasters, the supply chain, or mental health services, a Sankey chart can provide valuable insights and help you make informed decisions.
