Title: Unlocking the Power of Sankey Charts: A Visual Guide to Exploring Hierarchical Relationships in Data

Sankey charts are powerful visual tools for exploring hierarchical relationships in data. These charts are an extension of the flow chart concept, and they provide a clear visual representation of the direction and strength of relationships between variables. This article will walk you through the steps for creating a Sankey chart and provide examples of their applications.

What is a Sankey Chart?

A sankey chart is a graphical representation of hierarchical relationships in data. They are also known as flow diagrams or bar charts with flow lines embedded in them. Sankey charts are typically used to show the flow of data or information from a source to a target, with flow lines representing each individual relationship.

How to Create a Sankey Chart?

Before you can create a sankey chart, you need to have a dataset that can be represented hierarchically. Once you have your data, you can use a computer program or spreadsheet to create a sankey chart. There are many programs available for creating sankey charts, such as Excel, Tableau, and Python libraries like matplotlib and plotly. Additionally, there are online tools that provide template sankey charts and tools that let you create Sankey charts more easily, such as this one.

Here are the five steps to creating a sankey chart:

Choose a template or design. Sankey charts have several templates that you can use, or you can design your own. Some templates are created by software like Tableau or software like plotly, while others are available for free online. Templates allow you to see the hierarchy of your data easily, and they can help you set up your chart.
Enter your data. Once you have created your template, you can enter your data. Data should be organized hierarchically, with variables on top and more specific variables at the bottom. Each variable should be a separate line, with the source at the top and the target at the bottom.
Draw the lines. In the top-left position of each variable, draw a line to the variable below. This line represents the “flow” or “exit” of the data. The top-right position of each variable should be the “source” of the data, with the line leading away from it.
Modify the data and lines. There are many ways to modify a sankey chart. You can add annotations to the lines to explain the flow or direction of the data. You can also increase or decrease the line width to help distinguish sources and targets.
Add additional data if desired. If your data contains multiple relationships, you can add more variables and lines to your sankey chart. This will help you explore more aspects of the hierarchies.

Illustrative Examples

Sankey charts can be applied in various fields and fields, such as economics, sociology, and psychology. For instance, in economics, sankey charts can be used to analyze the flow of capital between different sectors, where the flow represents the amount of investment, and the target represent the sources of capital. In sociology, sankey charts can be used to analyze social hierarchies, showing how resources and roles flow between different actors. In psychology, sankey charts can show how motivation, stress, and other factors flow between different variables.

Conclusion

Sankey charts are a powerful visual medium for understanding hierarchical relationships in data. By following the steps above, you can create a clear and easy-to-understand sankey chart. You can use them to represent a variety of fields, allowing you to explore the flow of information and data in a way that traditional tables and diagrams cannot. With this medium, you can gain a deeper understanding of the relationships present in your data, helping you make better data-driven decisions.
