Visualizing Flow: The Power of Sankey Charts

Sankey charts are a type of flowchart that can be used to visualize the movement of items or processes between different components or actors. These charts are named after Irish physicist and chemist L. Sankey, who developed the technique in the late 19th century. Sankey charts are particularly useful for visualizing complex systems where multiple paths or streams can occur.

Creating a Sankey Chart

Sankey charts are created using a specialized software program called Visio or PowerPoint. The process of creating a Sankey chart involves several steps:

1. Determine the source and destination points for your chart.
2. Identify the flow of items or processes between these points, and label each step with a description or identifier.
3. Choose the appropriate Sankey chart type, such as a directed or directed/reversed chart.
4. Customize the chart with colors, lines, and other visual elements to enhance the clarity and impact of the chart.

Using Sankey Charts

Sankey charts can be used to visualize a wide range of processes or systems, including supply chain management, financial transactions, and social networks. Some potential uses of Sankey charts include:

1. Identifying bottlenecks or areas of inefficiency in a process.
2. Visualizing the flow of goods or services through a supply chain.
3. Analyzing the movement of people or ideas between different groups or locations.
4. Demonstrating the impact of different decision points or policy changes on a process or system.

Conclusion

Sankey charts are a powerful tool for visualizing complex flow systems, and can be used to gain insight and improve processes. By creating and using Sankey charts, individuals and organizations can better understand their systems and identify opportunities for improvement.
