Sankey charts are a powerful and flexible data visualization tool that can be used to show the flow and transformation of data. Unlike other types of charts, such as bar charts or line charts, Sankey charts enable users to see the relationships between different data points in a more intuitive and visually appealing way.
In this article, we will explore the basics of Sankey chart creation, as well as some of the many applications for which they are commonly used. We will also look at best practices for using Sankey charts effectively, and discuss some tips for creating compelling and informative visualizations using this powerful tool.
Creating Sankey Charts
Sankey charts are essentially flow diagrams that can be used to show the movement of data between different entities. They are created by using a set of interconnected nodes, each of which represents a data point, and arrows, which represent the flow of data between those points.
To create a Sankey chart, you will need to have a data set that includes at least two entities, as well as the data points that represent those entities. You will then need to specify the relationships between those entities, using arrows to indicate the direction and type of flow.
There are several software applications that you can use to create Sankey charts, including Microsoft Power BI, Google Data Studio, and Tableau. Some of these applications also offer additional features, such as the ability to customize the appearance of your chart, or to add additional data to your chart in real-time.
Applications of Sankey Charts
Sankey charts are widely used in a variety of industries and fields, including finance, marketing, and operations management. Some of the common applications for Sankey charts include:
- Identifying the flow of data between different entities, and identifying potential bottlenecks or inefficiencies in that flow.
- Analyzing the sources and destinations of data, and understanding how data is transformed or processed as it flows between those entities.
- Tracing the origin of a particular piece of data, and understanding where it came from and how it was transformed before it reached its final destination.
- Identifying trends or patterns in the flow of data, and using that information to make informed decisions.
Using Sankey Charts Effectively
There are several best practices that you can follow when using Sankey charts to create effective and informative visualizations:
- Use a clear and consistent set of symbols and colors to represent different data points and relationships.
- Use arrows to clearly indicate the direction and type of flow between data points.
- Use labels and annotations to provide context and additional information about the chart.
- Customize the appearance of your chart to fit your specific needs and preferences.
- Use real-world examples or illustrations to make your chart more relatable and engaging.
- Use Sankey charts in conjunction with other types of charts, such as bar charts or line charts, to provide a more comprehensive view of your data.
- Be mindful of the size and scale of your chart, and ensure that it is easily readable and understandable.
Conclusion
Sankey charts are a powerful and flexible data visualization tool that can be used to show the flow and transformation of data in a visually appealing and intuitive way. They are commonly used in a variety of industries and fields, and can be created using a range of software applications. Best practices for using Sankey charts include using clear and consistent symbols and colors, providing additional context and information through labels and annotations, and customizing the appearance of your chart to fit your specific needs and preferences.
