Sankey charts are a powerful visualization tool for understanding flow and transformation in complex systems. They are particularly useful for analyzing the movement of materials, energy, or information between different components of a system. In this article, we will explore the basics of creating Sankey charts and some of the many applications for this type of visualization.

What is a Sankey Chart?

A Sankey chart is a type of flowchart that uses directed arrows to represent the movement of materials, energy, or information between different components of a system. Unlike traditional flowcharts, which use loops to represent decisions or cycles, Sankey charts use directed arrows to represent the flow of materials or energy through a system. This makes it possible to easily see the relationships between different components of a system and how they impact each other.

Creating a Sankey Chart

To create a Sankey chart, you will need a flowcharting tool that supports this type of visualization. Some popular options include Microsoft Visio, Lucidchart, and SmartDraw. Once you have chosen a tool, you can follow these steps to create a Sankey chart:

1. Open your flowcharting tool and create a new chart.
2. Select the first shape that you want to use as the source for your Sankey chart. This will typically be the area where materials or energy enter the system.
3. Choose the direction of the flow that you want to represent. For example, if you are representing the flow of materials, you will choose “incoming” as the direction.
4. Create a new shape that will represent the first step in the process. This will typically be the first place where materials or energy are transformed or used.
5. Connect the first shape to the next shape using a directed arrow. This arrow should represent the direction of the flow.
6. Repeat step 5 for each step in the process until you have reached the final destination or sink.
7. You can add additional shapes and text as needed to further customize your Sankey chart.

Applications of Sankey Charts

Sankey charts are widely used in fields such as logistics, supply chain management, and environmental studies to visualize the flow of materials or energy through a system. Some specific applications of Sankey charts include:

1. Analyzing the environmental impact of a product or process: Sankey charts can be used to show the flow of materials or energy through a system and identify areas where waste or pollution are generated.
2. Tracking inventory and supply chain management: Sankey charts can be used to visualize the flow of inventory between different locations in a supply chain, helping to identify bottlenecks and areas for improvement.
3. Modeling energy usage and efficiency: Sankey charts can be used to show the flow of energy through a system, highlighting areas where energy is wasted or lost.
4. Understanding water flow and pollution: Sankey charts can be used to visualize the flow of water through a system, helping to identify sources of pollution and areas for improvement.
5. Analyzing financial transactions: Sankey charts can be used to show the flow of money or other financial resources between different parties in a transaction or investment.

In conclusion, Sankey charts are a powerful visualization tool for understanding flow and transformation in complex systems. They are particularly useful for analyzing the movement of materials, energy, or information between different components of a system. By following the steps outlined above, you can easily create your own Sankey chart to gain insights into the flow of materials or energy in your system.
