Sankey charts are a visual representation of how data flows through different segments of a system. They are a powerful tool for understanding complex processes and the various relationships between different elements in a system.

In this article, we will guide you through the process of creating a chart and understanding the applications of Sankey charts.

What Are Sankey Charts?
Sankey charts are a type of flowchart that represents the different paths or flows of data in a system. The chart is made up of multiple segments or nodes, which represent different parts of the system, and lines connecting those segments to represent the data flow.

Each node in the chart corresponds to a different segment of the data flow, and the length and orientation of the connecting lines represent the magnitude of the data flow between the segments.

Sankey charts are useful for visualizing the relationships between different elements in a system, such as how different departments or projects are related, and how the flow of data between them can be optimized.

How to Create a Sankey Chart
Creating a Sankey chart is a relatively simple process that can be done using a spreadsheet program like Microsoft Excel. Here is an outline of the steps involved:

1. Gather data: The first step is to gather the data that you want to represent in your Sankey chart. This could include information on the flow of any type of data, such as employee productivity, project completion, or customer turnover.

2. Determine the segments: Next, you need to determine the different segments that will be included in your Sankey chart. These segments should correspond to the different departments, projects, or other elements that are being represented.

3. Create a diagram: Create a diagram of the segments with a few of the data flow lines connecting them. The number of segments and data flow lines in your chart will depend on the amount and type of data you want to represent.

4. Calculate the flow: Calculate the flow of data between each pair of segments. The flow calculation can be done manually by hand, or if you are using a spreadsheet program, you can use the same techniques as you would with a standard flowchart.

5. Add the data flow lines: Once you have calculated the flow between each pair of segments, add the corresponding lines to your Sankey chart to visualize the flow.

6. Format your chart: Finally, format your chart to make it clearer and more visually appealing. This may involve adding appropriate labels and color schemes.

How to Understand Sankey Charts
Sankey charts can be confusing at first glance, but once you understand how they work, they can be a powerful tool for understanding complex processes.

To understand the Sankey chart, follow these steps:

1. Start by understanding the data flow between the segments. Look for patterns and trends in the data to help make sense of the chart.

2. Consider the purpose of the chart. Is it helping you identify potential bottlenecks in a process, or identify opportunities for improvement?

3. Use the chart to communicate the information it represents. If you are presenting the Sankey chart to a team, make sure everyone understands its meaning and implications.

Conclusion
Sankey charts are a powerful visual tool for understanding complex processes and the relationships between different elements in a system. Whether you are analyzing employee productivity, project completion, or customer turnover, a well-designed Sankey chart can help you make sense of the data and identify opportunities for improvement. With practice, you can create a wide variety of Sankey charts that can help you understand and improve any process.
