Sankey charts are a type of data visualization that are particularly well-suited for showing flows and relationships between different categories or variables. This article will delve into the basics of how to create Sankey charts, as well as highlight some of the many applications of these charts in fields such as economics, energy, and environmental science.
Creating a Sankey Chart
A Sankey chart is made up of two main components: nodes and links. Nodes represent the different categories or variables in the data being visualized, and links represent the flow of data between those categories. These links are often depicted as arrows, which can be used to show the direction and magnitude of the flow.
To create a Sankey chart, you will need to start by organizing your data in a table or spreadsheet. The data should include information about the nodes and links, such as the names of the categories being compared, the direction of the flow, and the magnitude of the flow (such as the number or percentage of items being transferred).
Once you have your data organized, you can use a data visualization tool or software, such as Tableau, Power BI, or R, to create the actual Sankey chart. These tools typically have intuitive interfaces that allow you to drag and drop your data into the appropriate fields, and then customize the look and feel of the chart with a range of options such as colors, labels, and annotations.
Applications of Sankey Charts
Sankey charts are particularly powerful when it comes to visualizing complex flows and relationships between different categories or variables. Some of the many applications of Sankey charts include:

1. Economics: Sankey charts can be used to visualize the flow of goods, services, and/or capital between different industries or regions. This can give insights into the interdependencies and trade flows within an economy.
2. Energy: Sankey charts can be used to show the flow of energy through different systems, such as power grids or fuel pipelines. This can help to identify inefficiencies, bottlenecks, and opportunities for optimization.
3. Environmental Science: Sankey charts can be used to show the flow of pollutants or other materials through ecosystems, as well as the impact of human activities on the environment.
4. Business: Sankey charts can be used to visualize the flow of customers or transactions through different stages of a business process, such as a sales or support pipeline. This can help to identify areas where improvements can be made, such as reducing friction or increasing conversions.

Conclusion
In summary, Sankey charts are a highly powerful and versatile type of data visualization that can be used to show complex flows and relationships between different categories or variables. By creating Sankey charts using the appropriate data organization and visualization tools, you can create compelling visualizations that provide insights and insights into a wide range of applications, from economics to environmental science to business analytics.
