Sankey charts are a type of data visualization that allows users to easily understand and analyze the flow of data or resources through a system. They are named after their inventor, an engineer named Anthony C. T. Sainteny, who used them to visualize the flow of energy in steam power plants. Today, Sankey charts are used in a wide variety of fields, from economics and engineering to environmental science and epidemiology, to help users better understand complex systems.

Creating a Sankey chart involves several steps. First, the data that you want to visualize must be gathered in a suitable format, typically a collection of nodes (representing the sources and sinks of the flow) and edges (representing the flow from node to node). This data can be collected using surveys, datasets, or other methods of data collection.

Next, software or tools can be used to create the chart. There are several Sankey chart creation tools available, both free and paid, that make it easy to create and customize the chart to your needs. Some popular tools include SankeyJS, Sankey, and Gephi. These tools typically allow you to input your data and customize various aspects of the chart, such as the width and color of the edges, the orientation and layout of the nodes, and the fonts and labels used.

Once the data and customization settings have been applied, the chart is ready to be visualized. The result is a clear and visually engaging representation of the data, that can help users understand how various components of the system interact, the distribution of resources, and the magnitude of the flows.

The power of Sankey charts really lies in their ability to help users visualize complex systems. In economics, for example, Sankey charts can be used to show the flow of goods and services between countries or regions, enabling users to understand trade patterns and opportunities for improvement. In environmental science, Sankey charts can be used to visualize the flow of energy and materials, enabling users to identify areas of waste and opportunities for conservation. In epidemiology, Sankey charts can be used to show the flow of infections between populations, enabling users to identify patterns and hotspots for outbreaks.

Overall, Sankey charts are a powerful tool for data visualization that can help users understand complex systems, uncover patterns and trends, and make informed decisions based on data. By using Sankey chart creation tools and following best practices for data visualization, users can create compelling and informative Sankey charts that can help them communicate their findings and insights to others.
