Sankey charts are a powerful visualization tool that allow you to easily see the flow of data and the relationships between different data sets. They are particularly useful for showing the movement of data between different processes or entities, and can be used to identify bottlenecks and opportunities for improvement. In this article, we will explore the basics of creating Sankey charts, as well as some common applications in business and data analysis.

How to Create Sankey Charts

Sankey charts are created using a spreadsheet program such as Microsoft Excel or Google Sheets. They are essentially a type of flowchart that uses arrows to show the movement of data between different entities. To create a Sankey chart, you will need to follow these steps:

1. Open a spreadsheet program and create a new chart.
2. Select the chart type as “Sankey chart.”
3. Enter the data for your chart into the cells provided. This will include the source and destination of each flow of data.
4. Customize the chart as desired, including adding titles, changing the colors of the arrows, and adjusting the layout.
5. Save the chart as a PNG or JPEG file and use it as needed.

Applications of Sankey Charts

Sankey charts are extremely versatile and can be used in a wide range of applications, including:

1. Business analysis: Sankey charts can be used to visualize the flow of data and identify bottlenecks and opportunities for improvement in a business process. For example, a company might use a Sankey chart to show the movement of raw materials from suppliers to production to customers.
2. Data analysis: Sankey charts can be used to visualize the flow of data across multiple data sets, making it easier to identify patterns and relationships. For example, a data analyst might use a Sankey chart to show the movement of data between different variables in a large dataset.
3. Process analysis: Sankey charts can be used to visualize the flow of data between different processes, making it easier to identify dependencies and areas for improvement. For example, a process improvement team might use a Sankey chart to show the movement of data between different stages of a manufacturing process.

In conclusion, Sankey charts are a powerful visualization tool that can help you see the flow of data and the relationships between different data sets. Whether you are working in business or data analysis, Sankey charts can be a valuable aid in understanding and improving complex systems. To create a Sankey chart, simply open a spreadsheet program, select the chart type, enter the data, and customize the chart as desired. Then, use the chart to gain insights and make improvements in your data and processes.
