In this article, we’ll take a deep dive into the creation and application of Sankey charts, including tips and best practices. We’ll also give you access to a wide range of free visualization tools that can help you create your own Sankey charts.
What is a Sankey Chart?
A Sankey chart is a type of diagram that draws attention to the flow of information, data, or resources from one point to another. It’s commonly used in social science research, business, and other fields where analyzing flow is essential.
The key components of a Sankey chart include a node and a link. A node represents the starting or ending point of the flow, while a link connects two nodes. You can use Sankey charts to represent data flows, energy flows, or any type of flow that requires visual representation.
Creating a Sankey Chart
When it comes to creating a Sankey chart, there are generally four steps you’ll need to follow:
1. Identify the data you want to visualize
2. Organize the data into components
3. Create links between the components
4. Arrange the components and links in a way that makes sense
To put it simply, you’ll need to take a look at the data you want to visualize, organize it, then create a network of links that represent the flow of information, data or resources. The result should be a Sankey chart that highlights the flow and draws attention to the significant components.
Best Practices for Creating a Good Sankey Chart
Once you’ve got a basic understanding of how to create a Sankey chart, here are some best practices to keep in mind to make sure you get the best visualization:
1. Keep it Simple: A Sankey chart should be simple and easy to understand. Avoid using too many colors, overly complex designs, or small details that don’t contribute to the overall message.
2. Use the Right Scale: Make sure the scale you choose for your Sankey chart represents the data you want to communicate well. A too large or too small scale can often cause confusion.
3. Use the Right Information: Make sure to only use the data you need to communicate to the audience. Avoid cluttering your chart with unnecessary details.
4. Add a Legend: A legend gives your audience an explanation of the symbols used in your chart. It also helps make your chart more accessible.
5. Use Color Coded Components: Color coding is an often used technique in Sankey charts to help communicate different components. Using colors can significantly improve the visual appeal and readability of your chart.
