Streamlining Your Process: Understanding and Utilizing Sankey Charts for Data Visualization

Data visualization is an essential tool in the modern business world. It helps to simplify complex information and present it in an easily digestible format. Sankey charts are a type of data visualization that are becoming increasingly popular due to their unique ability to show the flow of data between different entities. In this article, we will explore how Sankey charts can be used to streamline your process and improve your data analysis.

What is a Sankey Chart?

A Sankey chart, also known as a directed flow chart, is a type of data visualization that is used to represent the flow of data between different entities. It is based on the Sankey algorithm, which was developed in the early 20th century. The algorithm allows for the creation of a chart that shows the direction and magnitude of the flow of data between different entities.

Sankey charts are particularly useful in showing the flow of data in complex systems. For example, they can be used to visualize the flow of goods or services between different departments within a company, or the flow of money between different accounts.

How is a Sankey Chart Created?

To create a Sankey chart, you will need to have a data source that contains information about the flow of data between different entities. This data will typically be in the form of a table or spreadsheet.

Once you have your data, you will need to import it into a charting tool that supports Sankey charts, such as Excel, Tableau, or PowerBI. There are many charting tools available that support Sankey charts, so you should choose the one that best fits your needs and budget.

Next, you will need to configure the chart based on your data. This will involve selecting the entities and directions on the chart, as well as setting other chart options, such as the colors and fonts.

Finally, you will need to customize the chart further, such as adding annotations or filters, to make it even more useful and informative.

Applications of Sankey Charts

Sankey charts can be used in various applications to help streamline and improve data analysis. Some of the common applications of Sankey charts include:

1. Supply Chain Management: Sankey charts are particularly useful in supply chain management as they can be used to visualize the flow of goods or services between different departments or suppliers. This can help to identify bottlenecks in the supply chain and improve efficiency.
2. Financial Analysis: Sankey charts can also be used in financial analysis to show the flow of money between different accounts or departments within a company. This can help to identify areas where costs can be reduced or revenue can be increased.
3. Process Optimization: Sankey charts can be used to visualize the flow of data within a business process or system. This can help to identify areas where the process can be streamlined or optimized for efficiency.
4. Customer Insights: Sankey charts can be used to visualize the flow of customer interactions within a business, such as phone calls, emails, or social media messages. This can help to identify areas where the customer experience can be improved and to better understand customer needs and preferences.

Conclusion

Sankey charts are a powerful data visualization tool that can be used to streamline and improve data analysis in various applications. They are particularly useful in supply chain management and financial analysis, but can also be used in process optimization and customer insights. By understanding how to create and use Sankey charts, businesses can gain valuable insights into their operations and make informed decisions to improve efficiency and increase profitability.
