Unleashing the Power of Sankey Charts for Understanding Data Flow

Sankey charts are a type of flowchart that can be used to visualize the flow of data or material through a system or process. They have been around since the 1800s, but they have become increasingly popular in recent years as data visualization tools become more sophisticated and accessible. In this article, we will discuss the basics of Sankey chart creation and some of the many ways they can be used to make sense of complex data flows.

Understanding Sankey Charts

Sankey charts are named after English physicist and chemist William Edward Sankey. He developed the chart in the late 1800s as a way to visualize the movement of gases through a system. Sankey charts are essentially flowcharts that use arrows and circles to represent the flow of data or material through a process. The arrows and circles are used to indicate the source and destination of the flow, and the size of the circles can represent the amount of data or material flowing through the process.

One of the key advantages of Sankey charts is that they can be used to represent a wide range of data flows, from chemical reactions to social networks. They are also particularly useful for identifying bottlenecks or inefficiencies in a process, and for visualizing the overall structure of a system.

Creating Sankey Charts

Sankey charts can be created using a variety of software tools, including Microsoft Visio, Lucidchart, and Gliffy. Many of these tools also offer pre-designed templates and themes that can be used to create Sankey charts quickly and easily.

To create a Sankey chart, you will need to import data or process flow information into the charting tool. This can be done using a spreadsheet or other data source, or by manually entering the data into the tool. Once the data is imported, it can be organized into nodes and links using the charting tool’s interface.

Using Sankey Charts to Visualize Data Flows

Sankey charts are a powerful data visualization tool that can be used to gain insights into complex data flows. Some of the ways in which they can be used include:

• Identifying bottlenecks or inefficiencies in a process: Sankey charts can be used to visualize the flow of data through a process, which can help identify any bottlenecks or inefficiencies that may be causing delays or problems.
• Analyzing trends and patterns: Sankey charts can be used to visualize the flow of data over time, which can help identify trends and patterns that may not be obvious when examining data in isolation.
• Understanding interconnections: Sankey charts can be used to visualize the relationships between different data feeds or processes, which can help identify dependencies or other interconnections that may be important to understand.

Conclusion

Sankey charts are a powerful data visualization tool that can be used to gain insights into complex data flows. They are particularly useful for identifying bottlenecks or inefficiencies in a process, analyzing trends and patterns, and understanding interconnections. With the increasing availability of data and the need to make sense of it all, Sankey charts are a valuable asset for anyone looking to gain a deeper understanding of their data.
