Sankey charts have become increasingly popular in the world of data visualization due to their ability to represent complex network relationships using an easily understandable diagram. They are particularly useful for data sets where information flows from one point to another, and they help to visually communicate the flow of data with an ease of interpretation.
A Sankey chart is a two-dimensional representation of a network, which is useful for visualizing the flow of data. In this article, we will explore some tips and tricks for creating and understanding Sankey charts, as well as some of the practical applications of these charts.
Tips and Tricks for Creating Sankey Charts

1. Start by understanding the data: Before you start creating your Sankey chart, it’s important to understand the data you’re working with. Make sure you have all the information that you need to create your chart.
2. Choose the right tools: There are several tools available for creating Sankey charts, including Tableau, Microsoft Excel, and Adobe Illustrator. Choose the one that suits your needs and the complexity of your data set.
3. Use color coding: In a Sankey chart, you can use color coding to represent the direction of the flow of data. For example, red can represent incoming data, blue can represent outgoing data, and green can represent the balance of flows.
4. Include labels: In a Sankey chart, it’s important to include labels to help make sense of the data. These labels should be clearly labeled and easy to understand.

Applications of Sankey Charts

1. Healthcare: Sankey charts can help healthcare professionals visualize the flow of resources between different departments or locations. This information can then be used to optimize distribution and ensure that resources are used more effectively.
2. Agriculture: Sankey charts can be used to visualize the flow of resources between different stages of production and the demand for certain products. This information can then help farmers optimize their production and increase their crop yields.
3. Financial: Sankey charts can be used to visualize the flow of resources between different accounts and the balance of each account. This information can then help businesses optimize their spending and increase their profits.
4. Education: Sankey charts can be used to visualize the flow of information between different subjects and the balance of each flow. This information can then help educators optimize their teaching methods and improve their learning outcomes.
