Sankey charts are a popular type of flow diagram that show the movement of quantities from one category to another. These charts can be used to visualize a variety of data, such as energy consumption, material flow, and transportation routes. In this article, we will explore the world of Sankey charts, including how to create them and some of the applications where they are most useful.
Creating Sankey charts
To create a Sankey chart, you will need to gather data on the flow of quantities between different categories. This data should be organized in a table format, with the categories listed along one axis and the quantities along the other. You will also need to determine the color scheme you want to use for the chart and consider the layout of the chart, such as whether you want it to be horizontal or vertical and whether you want the flows to be shown in the foreground or the background.
One popular tool for creating Sankey charts is the open-source library, D3.js. D3.js provides a wide range of features for creating interactive charts and is well-supported by the online community. To create a Sankey chart with D3.js, you will need to write JavaScript code that defines the data, layout, and styling of the chart. Once your code is written, you can use a web browser to visualize the chart and interact with it.
In addition to D3.js, there are other tools available for creating Sankey charts, such as Sankey Chart Creator, which is a user-friendly tool that allows you to easily create custom Sankey charts.
Applications of Sankey charts
Sankey charts can be used for a wide range of applications, including:

1. Energy consumption and distribution: Sankey charts can be used to visualize energy consumption and distribution across different sources and processes. This can be useful for identifying areas where energy use can be reduced and for optimizing energy systems.
2. Material flow analysis: Sankey charts can be used to analyze material flow in manufacturing processes, supply chains, and other industries. This can help identify bottlenecks and improve material flow.
3. Transportation analysis: Sankey charts can be used to visualize transportation routes and flows, such as shipping and distribution routes or public transportation networks.
4. Data visualization: Sankey charts can be used to create visually appealing data visualizations that convey complex information in an intuitive way. This can be useful for communicating data to stakeholders or for presenting key findings in reports.
5. Health and wellness: Sankey charts can be used to visualize the flow of nutrients, energy, and other factors in the body and in health systems. This can help identify areas where improvements can be made and support research into optimal health and wellness.

Conclusion
In conclusion, Sankey charts are a powerful tool for visualizing flow data in a variety of applications. By using open-source libraries such as D3.js, users can easily create customized visualizations that are both informative and visually pleasing. Whether you’re analyzing energy consumption, optimizing supply chains, or supporting research into health and wellness, Sankey charts can help you communicate your findings in a clear and intuitive way.
