Sankey charts are a powerful and visually appealing way to visualize data flow and efficiency in a data analysis. They are especially useful in complex systems where multiple interconnected processes are present, and in understanding their interactions. In this article, we will explore the basics of creating Sankey charts, their applications, and how to get the most out of them.

What is a Sankey chart?

A Sankey chart is a type of flowchart that highlights the flow of materials, information, or energy between different entities. It is named after its creator, Japanese engineer and statistician, H. Sankey. Sankey charts are particularly useful for visualizing the relationships between different components of a complex system, such as a supply chain, financial system, or a biological ecosystem.

How to create a Sankey chart?

There are several software programs that can be used to create Sankey charts, including Microsoft Excel, Google Sheets, Lucidchart, and Visio. Here is an example of how to create a Sankey chart in Microsoft Excel:

1. Open Microsoft Excel and create a new workbook.
2. Enter some data into the first cell of a new sheet. This data will be the starting point of the flowchart.
3. Select the cell with the starting data, and then go to the Insert tab in the ribbon.
4. Click on the Sankey chart icon and select the Sankey chart option.
5. Customize the chart as desired, such as changing colors, adding labels, or modifying the flow lines.
6. The Sankey chart will be added to the worksheet and can be edited and saved as needed.

How to use Sankey charts in data analysis?

Sankey charts are a highly effective tool for visualizing data flow and efficiency in complex systems. Here are some ways they can be used in data analysis:

1. Supply chain analysis: Sankey charts can be used to visualize the flow of materials, goods, or services between different entities in a supply chain. This can help identify bottlenecks, inefficiencies, and potential risks.
2. Financial systems analysis: Sankey charts can be used to visualize the flow of funds, investments, or cash between different accounts in a financial system. This can help identify areas where funds are being misused or diverted.
3. Biological ecosystem analysis: Sankey charts can be used to visualize the flow of nutrients, energy, or pollutants between different components of a biological ecosystem, such as plants, animals, or microorganisms. This can help identify areas of overuse or depletion, as well as potential areas for conservation or restoration.
4. Social network analysis: Sankey charts can be used to visualize the flow of information, connections, or interactions between different individuals or entities in a social network. This can help identify key players or nodes, as well as potential areas for intervention or intervention.

Conclusion

Sankey charts are a valuable tool for visualizing data flow and efficiency in complex systems. They are easy to create using a variety of software programs, and can be used in a wide range of applications, from supply chain and financial systems analysis to biological ecosystem and social network analysis. By leveraging the power of Sankey charts, data analysts and managers can gain deeper insights into their data and make more informed decisions about how to optimize processes and improve efficiency.
