Sankey charts are a type of flowchart that are used to visualize the movement of items or resources between different nodes or regions. They are particularly useful in understanding and optimizing processes, identifying bottlenecks, and designing efficient systems. In this article, we will explore the basics of Sankey chart creation and the many applications of these powerful visual aids.

What are Sankey Charts?
Sankey charts were originally developed by British engineer Henry G. Sankey in the late 19th century as a tool for analyzing the flow of goods and resources between different regions. Today, they are widely used in various fields, including engineering, logistics, marketing, and finance. Sankey charts are particularly helpful in identifying and addressing bottlenecks in processes and optimizing the flow of resources.

How to Create Sankey Charts
Creating a Sankey chart is relatively easy, particularly with the help of specialized software. The basic steps for creating a Sankey chart are as follows:

1. Identify the source and sink nodes: The source node represents the input or starting point for the process, and the sink node represents the output or end point.
2. Add the nodes: Draw lines between the source and sink nodes to represent the flow of items or resources.
3. Assign values to the nodes: Label each node with the value or amount of items or resources that flow through it.
4. Draw arrows: Connect the source node to the nodes representing the input and connect the sink node to the nodes representing the output.

There are many software programs and templates available that can help you create and customize Sankey charts. Some of the most popular programs include Visio, Lucidchart, SmartDraw, and Gliffy.

Applications of Sankey Charts
Sankey charts are versatile and can be used in a variety of settings and industries. Some of the common applications of Sankey charts include:

1. Process optimization: Sankey charts can be used to identify and eliminate bottlenecks in processes and improve efficiency.
2. Resource management: Sankey charts can be used to track the movement of resources, such as money or materials, and identify areas where resources may be wasted or underused.
3. Supply chain management: Sankey charts can be used to visualize the flow of goods and materials between different nodes in a supply chain.
4. Marketing and sales: Sankey charts can be used to visualize the flow of customers or prospects through a sales or marketing process.
5. Environmental management: Sankey charts can be used to visualize the flow of pollutants or resources in an ecosystem.

Conclusion
Sankey charts are a powerful and flexible visual tool that can be used to understand and optimize flow and transportation processes. By following the basic steps outlined in this article and experimenting with different software and templates, you can createSankey charts to suit your specific needs and applications. Whether you are an engineer, marketer, or environmental manager, Sankey charts can help you gain valuable insights and improve the efficiency and effectiveness of your processes.
