Sankey chart is a powerful tool to display complex network data, which can be used to visualize relationships between different sets of data. In this article, we will provide an overview of how to create and use Sankey figures, as well as some common applications of these charts. We’ll also discuss the key features and limitations of Sankey charts, how to interpret them, and some best practices for reading them.
What is Sankey chart?
A Sankey chart is a type of chart that uses a series of horizontal lines to represent the flow of data between different sources and destinations. Each line has an input and output capacity, which determines how much data can pass through it at any time.
Sankey charts are commonly used to visualize the flow of information or resources between different sets of data, such as financial flows, resource allocation, or communication networks. They can be useful for understanding complex relationships between different types of data, as well as discovering underlying patterns and trends.
How to Create a Sankey Chart
Sankey charts are relatively simple to create, and there are several free tools available that make it easy to get started. Here’s a quick overview of the steps involved:
-
Choose your data. First, you need to identify the sources, destinations, and capacity for each line in your Sankey chart.
-
Design the layout. Decide where each source and destination will be placed on the chart, and adjust the size and orientation of the lines to match the data.
-
Add text labels. On each line, label the input and output capacity, as well as the direction of the flow.
-
Color-code the data. Use different colors or shades of the same color to differentiate between different types of data flow.
-
Add notes or explanations. If you have additional information or comments about the data being displayed, you can add notes or labels to the chart.
Common applications of Sankey charts
Sankey charts can be used in a variety of situations to explore complex relationships between data sources and destinations. Here are some common applications:
• Network analysis: Sankey charts can be used to explore the flow of information or resources between different types of nodes, such as a social network or a network of production facilities. This can help identify patterns, trends, and bottlenecks in the flow of data.
• Resource analysis: Sankey charts can be used to visualize the flow of scarce resources between different types of projects or facilities. This can help identify areas for optimization or resource allocation.
• Supply chain analysis: Sankey charts can be used to visualize the flow of resources between different stages of a supply chain, such as raw materials, manufacturing, and delivery. This can help identify bottlenecks and areas for improvement.
• Research data visualization: Sankey charts can be used to visualize complex data that is difficult to interpret using traditional chart types. This can help researchers explore the relationships between different variables and identify insights.
Best practices for reading Sankey charts
Sankey charts can be complex to interpret, so it’s important to take some time to familiarize yourself with the different elements and use patterns when reading them. Here are some best practices:
1) Start by focusing on the flow of data and the direction it is being directed in. This will help you understand how the data is being used and if it is flowing in the intended direction.
2) Look for clusters of lines or areas of high or low capacity. These can indicate areas of high demand or supply, as well as areas where there may be bottlenecks.
3) Consider the color or shade of the lines. Depending on the scale of the data, the lines may have different colors or shades, which can help you identify areas of great flow.
4) Use the notes and labels to understand the meaning behind the data. The information provided on each line can give you insights into the type of data and the direction it is flowing.
Conclusion
Sankey charts are a simple and effective tool for visualizing complex dataflows between different types of data sources and destinations. By following these best practices and being aware of the key elements and key directions, you can effectively use Sankey charts to explore and understand the relationships between your data.
