Sankey charts are a powerful visual storytelling tool that can be used to explore complex data in a clear and concise way. These charts were introduced by John F. Sankey in 1974 and have since been widely used in various fields, including economics, social science, and engineering.
One of the key advantages of using a Sankey chart is that they offer a unique perspective on data that can reveal hidden relationships or dependencies. This can be especially useful when working with complex networks or relationships between different entities. Sankey charts can be used to visually represent various types of complex data, including traffic flow, water flows, flows of nutrients in ecosystem, flows of money in a flow chart and so on.
The most basic form of a Sankey chart consists of two overlapping circles representing two sources and two sinks. The circles are connected by a network of lines representing the flow of data, with the length of the lines indicating how much data flows from one source to another. Each line in the chart can represent the flow of various types of data, such as money, energy, water, or resources.
Sankey charts can be used to visually compare and contrast different data sets, or to highlight important clusters or relationships. For example, a Sankey chart can be used to show the flow of resources from one region to another, highlighting regions that are receiving more or less resources than others. Or, a Sankey chart can be used to compare different models of electricity distribution, showing how each model affects the flow of electricity and resources.
Sankey charts can also be used to compare different scenarios or scenarios. By overlaying multiple Sankey charts on the same chart, researchers can compare the relative strengths or weaknesses of different models or scenarios. This can help researchers identify patterns or trends in data that may be hidden by simpler visualizations.
In summary, Sankey charts offer a unique way to explore and visualize complex data in a clear and concise way. With their ability to highlight relationships and clusters in data, these charts can be used to reveal important patterns or trends that would be difficult to identify through other types of visualizations. Whether you are researching economics, social science, or engineering, a Sankey chart can provide valuable insight into the data and help you better understand the relationships and dependencies between different entities.
