Streamlining Your Flow: A Guide to Mastering Sankey Charts

Sankey charts are a powerful visualization tool used to show the flow of materials, energy, or information through a system. They are particularly useful for understanding and optimizing complex processes. In this guide, we will explore the basics of Sankey chart creation and applications.

What is a Sankey Chart?

A Sankey chart is a type of flow diagram that is used to show the flow of materials, energy, or information through a system. It is named after the designer, George Sankey, who developed the chart in the 1930s. The chart represents the flow of materials or energy through a system by connecting nodes (also known as units) and arrows that show the direction and amount of flow between them.

Sankey charts are particularly useful for visualizing and understanding complex systems. They can be used to represent a wide range of systems, including chemical reactions, manufacturing processes, supply chains, and social networks.

How to Create a Sankey Chart

Creating a Sankey chart is straightforward, provided you have access to the software that supports the chart type. Some popular software programs that allow you to create Sankey charts include:

1. Lucidchart: A web-based diagramming tool that offers a variety of chart types, including Sankey charts. Lucidchart provides a user-friendly interface that is easy to navigate, even for users who are new to flowcharting.
2. Microsoft Visio: A professional flowcharting software that comes preinstalled with Microsoft Office. Visio has a large library of chart types, including Sankey charts, and offers advanced features for creating complex diagrams.
3. SmartDraw: A flowcharting and diagramming software that offers a wide range of templates and chart types. SmartDraw is user-friendly and easy to navigate, making it ideal for users of all skill levels.

Once you have chosen your preferred software, follow these steps to create a Sankey chart:

1. Select the flowchart type: Choose Sankey chart from the list of available chart types.
2. Add nodes: Add the nodes (units) that will represent the various stages in the flow.
3. Add arrows: Add arrows to show the direction and amount of flow between the nodes.
4. Customize the appearance: You can customize the appearance of your Sankey chart by changing the colors, fonts, and other settings.
5. Save and export: Save your Sankey chart and then export it in a variety of formats, including PDF and PNG.

Applications of Sankey Charts

Sankey charts are valuable tools for understanding and optimizing complex processes. Here are some key applications of Sankey charts:

1. Supply Chain Management: Sankey charts can be used to visualize the flow of materials or information through a supply chain. This helps identify bottlenecks and inefficiencies in the chain, allowing companies to make improvements to optimize efficiency.
2. Environmental Sustainability: Sankey charts can be used to visualize the flow of materials or energy through an environmental system. This helps identify areas where resources are wasted, and allows for the development of strategies to reduce waste and improve efficiency.
3. Economic Analysis: Sankey charts can be used to visualize the flow of money or other economic resources through a system. This helps identify areas where resources are misallocated, and allows for the development of strategies to optimize the flow of resources.

Conclusion

Sankey charts are a powerful visualization tool for understanding and optimizing complex processes. They are particularly useful for visualizing the flow of materials, energy, or information through a system. By following the steps outlined in this guide, you can create your own Sankey chart and begin to see the flow of materials or energy through your system in a new light. From supply chain management to environmental sustainability, Sankey charts offer valuable insights
