Sankey charts are a type of data visualization that can be used to explore and understand complex data flows. These charts are commonly used in fields such as economics, engineering, and social sciences, where the relationships between different elements of a system are important to understand.

In this article, we will explore the basics of how to create a Sankey chart and how to interpret the information that it can provide.

Creating a Sankey chart
To create a Sankey chart, you will need to gather data about the relationships between different elements in your system. This data can be in the form of numbers, labels, or even simple words or phrases. Once you have your data, you can begin to design your chart.

The basic layout of a Sankey chart consists of two main elements: the source and the target. The source is the element that is receiving the flow of information, and the target is the element that is sending the flow of information. The length of the arrows between the source and target elements represents the amount of flow that is being sent.

To add elements to your chart, you can use a variety of tools and software. Some popular options include Microsoft Excel, Tableau, and Google Sheets. Each of these tools has its own unique features and capabilities, so you may need to experiment with different options to find the one that works best for you.

Interpreting a Sankey chart
Once you have created your Sankey chart, you can begin to interpret the information that it can provide. The most important aspect of a Sankey chart is the direction of the arrows, as they indicate the flow of information between different elements. You can also look at the length of the arrows to determine the amount of flow being sent, as longer arrows typically indicate more flow.

Additionally, you can use Sankey charts to explore the relationships between different elements in a system. For example, if you have a chart that shows the flow of information from the source (a university) to the target (students), you can use this information to explore the impact of certain policies or initiatives on student recruitment.

Sankey charts can be a powerful tool for understanding complex data flows, but they can also be challenging to interpret. To get the most out of your Sankey chart, you will need to take the time to carefully consider the data and the information that it provides.

In conclusion, Sankey charts are a valuable tool for exploring complex data flows and relationships. By carefully designing your chart and interpreting the information that it provides, you can gain valuable insights into the systems and processes that you are working with. With practice and experimentation, you can create Sankey charts that are both informative and visually appealing.
