Transforming visualizations with Sankey charts can significantly enhance your data analysis tools’ effectiveness. Sankey diagrams are a type of network visualization that utilizes the flow of data to represent relationships between data sources and sinks. This type of diagram can help you clearly identify the flow of information or resources between different sets of data.
In this article, we will take a look at the creation and application of Sankey charts, along with the best practices for creating effective visualizations.
What is a Sankey Chart?
A Sankey diagram is a visual representation of the flow of information or resources between different sets of data. It is a type of network visualization that uses the flow of data to represent the flow between data sources and sinks.
Sankey diagrams can be used to show the flow of data or resources from one source or sink to another, as well as the flow of information or resources between different sets of data. They are commonly used in data analysis, risk assessment, and other fields that require the visualization of information flow.
How do you create a Sankey chart?
Creating a Sankey chart is relatively easy, and there are several tools and libraries available that can help you create effective visualizations quickly and easily. Here are the steps to create a Sankey chart:
- Determine the data source and sink: Identify the data sources and sinks that you want to display in your Sankey chart.
- Sort the data: Organize the data by the order in which you want it to be displayed. The order can be the source to sink or the sink to source.
- Choose the appropriate labeling scheme: Decide on the labeling scheme for your data sources, sinks, and arrows. The most common schemes are left-to-right and right-to-left arrows. Some diagrams also use circular labels, which can be useful for representing the flow of information or resources between different sets of data.
- Choose the appropriate visualization library: There are several tools and libraries available for creating Sankey diagrams, including D3.js, Chartist, and InfluxDB. Choose a library that fits your needs and expertise.

Now that you know how to create a Sankey chart, let’s take a look at how to use it effectively.
Best practices for creating effective Sankey charts
There are several best practices for creating effective Sankey diagrams. Here are a few tips:
- Keep it simple: Sankey diagrams can become complex if you try to cram too much information into them. Start with a single data set and gradually add more data as needed, as this will make the diagram more effective and easier to understand.
- Use colors and fonts: Use colors and fonts to distinguish between different sets of data, as this will make the diagram more readable and easier to understand.
- Use arrows to indicate the flow of information: Use arrows to indicate the flow of information or resources between different sets of data. The arrows should be directed from the source to the sink, or vice versa. Additionally, use arrows to indicate changes in flow, such as a decrease in flow or an increase in flow.
- Add labels: Add labels to your Sankey chart to show the direction of flow and the flow rate. This can help you visualize the flow of information or resources more effectively and understand the relationships between data sources and sinks.
Conclusion
Sankey charts can be a powerful tool for visualizing information flow and relationships between data sources and sinks. By following the best practices outlined above, you can create effective Sankey diagrams that will help you better understand your data and identify relationships between different sets of data. With the right tools and expertise, you can create Sankey diagrams that are not only effective but also visually appealing.
