Sankey charts are a type of network chart that are used to visualize the flow of data between different entities. They are particularly useful for identifying opportunities and trends in complex systems. In this article, we will discuss how to create Sankey charts, as well as some of the applications of this powerful visualization tool.

How to Create Sankey Charts

Sankey charts can be created using a variety of software tools, including Microsoft Excel, Lucidchart, and ManyCharts. Some of the key steps for creating a Sankey chart include:

1. Importing data: The first step in creating a Sankey chart is to import the data that will be used to create the chart. This can be done in a variety of ways, such as importing a spreadsheet or linking to a database.
2. Creating the chart: Once the data has been imported, the next step is to create the chart itself. This involves adding the different entities and their associated streams, and connecting these streams with arrows to represent the flow of data.
3. Customizing the chart: There are many different options available for customizing Sankey charts, including the ability to change the colors and styles of the entities and streams.

Applications of Sankey Charts

Sankey charts have a wide range of applications, including:

1. Process mapping: Sankey charts are particularly useful for mapping out the flow of a process, from start to finish. This can help identify areas where improvements can be made and bottlenecks can be addressed.
2. Data visualization: Sankey charts are an effective way to visualize large amounts of data and can help identify patterns and trends that might not be visible using other types of charts or graphs.
3. Product flow: Sankey charts can be used to visualize the flow of products through a manufacturing process, which can help identify opportunities for optimizing or improving the process.
4. Customer flow: Sankey charts can also be used to visualize the flow of customers through a sales or service process, which can help identify areas where customer satisfaction can be improved.

In conclusion, Sankey charts are a powerful visualization tool that can be used to visualize the flow of data in a wide range of systems. They are particularly useful for identifying opportunities and trends in complex systems, and can be used in a variety of applications, including process mapping, data visualization, product flow, and customer flow. By leveraging the power of Sankey charts, you can gain new insights and make more informed decisions about your systems and processes.
