Sankey charts, also known as Sankey diagrams, are a type of flowchart that are particularly useful for visualizing energy flows and ecosystem dynamics. They are named after the English physicist and chemist Frederick S Sankey, who developed the method in the late 19th century.
Sankey charts are a type of directed graph, where the flow of a particular substance or energy is represented by an arrow pointing from the source of the substance or energy to its destination. The chart also includes a set of weights or labels that represent the magnitude of the flow.
One of the main advantages of using Sankey charts is their ability to clearly and easily show the flow of a particular substance or energy through a system. This can be particularly useful for understanding and visualizing complex systems like ecosystems, where multiple interacting processes can take place.
Another advantage of using Sankey charts is that they can be easily customized to show different types of flows and systems. By changing the types of substances or energies that are represented in the chart, and by adjusting the weights or labels to show different magnitudes of the flows, researchers and analysts can create a chart that is tailored to their specific needs.
There are many ways that Sankey charts are used in scientific research and analysis. For example, they can be used to visualize the flow of energy through an ecosystem, showing how energy is passed from one species to another. This can help researchers better understand how different species interact and how energy is transferred through the system.
Sankey charts can also be used to visualize the flow of matter or pollutants through a particular system, such as a river or a metabolic pathway. This can help researchers understand the transport and transformation of substances within a system.
In addition to their use in scientific research and analysis, Sankey charts are also used in business and industry to help companies understand and optimize their supply chains. By visualizing the flow of goods and materials through a system, companies can identify bottlenecks and inefficiencies, and make changes to improve the efficiency of their operations.
Overall, Sankey charts are a powerful tool for visualizing energy flows and ecosystem dynamics, and for understanding the complex systems that underlie our world. They can be used in a variety of settings and contexts, helping us to better understand and navigate the systems around us.
