Sankey charts are a type of network visualization that are commonly used to visualize and analyze complex data networks. They are particularly useful for showing proportional flow between sources and sinks, which is often represented by lines or arrows. In this article, we will explore how to create and understand Sankey charts, as well as examples of their applications.
Creating a Sankey Chart
To create a Sankey chart, you will need to have a set of data that you want to plot and analyze. You can use the data in the form of a table, a graph, or a spreadsheet. Once you have your data, you can start by selecting the nodes and edges that represent your data. Nodes are typically the source or sink regions, while edges are arrows that show flow between the nodes. Once you have your data and nodes/edges defined, you can use a software tool to create a Sankey chart.
One of the benefits of using a Sankey chart is that it is very simple to understand. The arrows are drawn in proportion to the flow between the nodes. This makes it easy to identify the flow direction and magnitude of different flows. Another benefit of Sankey charts is that they can be easily shared and interpreted. They can be used to communicate the complexity of data in a visual manner.
Applications of Sankey Charts
Sankey charts are used in various applications, including:
-
Energy use: Sankey charts can be used to show the energy used by buildings, hospitals, or any other source. For instance, you can display how much energy is used at a source like a furnace and flow towards sinks like rooms or living spaces.
-
Healthcare: Sankey charts can show the flow of healthcare resources like doctors, nurses, and hospitals. It’s effective for showing how much is being used for each element.
-
Traffic: Sankey charts can visualize the flow of people and traffic in a city, hospital, or anywhere. They can help identify bottlenecks and potential areas of congestion.
-
Science and technology: Sankey charts can be used to show the flow of data or information from one node (source) to another (sink). It can be used for projects, collaborations, or just to get a better understanding of the data flow between different groups.
Conclusion
Sankey charts are a powerful tool for visualizing complex data networks. They are relatively easy to create, understand, and share. With their many applications, they have become a go-to tool for analysts, researchers, and businesspeople alike. They provide a clear and concise way to visualize the flow of data and can help identify areas for improvement.
