Sankey charts are a type of flowchart that are used to visualize the flow of data, materials, or information between different entities or processes. They are an effective tool for understanding and optimizing resource allocation, and can be used to identify bottlenecks and areas for improvement in a system. In this article, we will explore the creation of Sankey charts, their applications, and how they can be used to make sense of complex data flow.

How to create Sankey charts

Sankey charts are created using a software tool called SankeyMiner. This tool is open-source and can be downloaded from the project’s GitHub repository. Once installed, users can import data in the form of an Excel spreadsheet and SankeyMiner will generate a Sankey chart for them.

To use SankeyMiner, follow these steps:

1. Download and install SankeyMiner from the GitHub repository.
2. Open Excel and create a new spreadsheet.
3. Copy and paste the data into the first column of the spreadsheet.
4. Open the SankeyMiner tool and select “Run and browse the charts”.
5. Choose the Sankey chart style you want to use.
6. Choose the entities or processes you want to visualize.
7. Click the “Run” button to generate the chart.
8. Browse the chart and make any necessary adjustments to the settings or data.

Applications of Sankey charts

There are many applications of Sankey charts, some of the most common include:

1. Resource allocation: Sankey charts can be used to visualize the flow of resources between different entities or processes and can help identify areas where resources are being underutilized or overused.
2. Supply chain management: Sankey charts can be used to visualize the flow of materials from suppliers to customers, and can help identify bottlenecks and areas for improvement in the supply chain.
3. Financial analysis: Sankey charts can be used to visualize the flow of money between different accounts or entities, and can help identify areas where resources are being underutilized or overspent.
4. Process improvement: Sankey charts can be used to visualize the flow of data or information through a process and can help identify areas where the process can be optimized for better efficiency or outcomes.

Conclusion

In conclusion, Sankey charts are an effective tool for visualizing data flow and resource allocation. They can be used to understand and optimize processes, identify bottlenecks and areas for improvement, and make sense of complex data flow. With the ability to import data in the form of an Excel spreadsheet, SankeyMiner makes it easy for anyone to create these powerful visualizations.
