Sankey charts are a powerful visualization tool for understanding the flow and transformation of data. They are particularly useful for visualizing complex systems, such as supply chain networks, financial transactions, and information flows. In this article, we will explore the creation and uses of Sankey charts, as well as tips for working with them effectively.
What is a Sankey chart?
Sankey charts are a type of flowchart that are used to visualize the flow of goods, services, or information between different nodes (also called “boxes”) in a system. Each box represents a different entity, such as a producer, distributor, or customer, and the arrows (or “lines”) connecting the boxes represent the flow of goods, services, or information between the nodes.
One of the unique features of Sankey charts is that they allow the viewer to see the direction of the flow as well as the amount of flow. This is achieved by using different colors or patterns for the arrows, as well as the width of the arrows. For example, arrows with a thicker line or a different color may represent a larger flow of goods, services, or information.
How are Sankey chartscreated?
There are a few different tools that can be used to create Sankey charts, such as Microsoft Visio, Lucidchart, or Gliffy. Many of these tools offer pre-made templates for Sankey charts, as well as the ability to customize the chart to fit your specific needs.
To create a Sankey chart, you first need to choose the nodes and arrows that will be used to represent the flow of goods, services, or information in your system. You can then connect the nodes using arrows, and use the chart’s features to customize the appearance of the chart.
Tips for using Sankey charts effectively
One of the key benefits of Sankey charts is that they allow you to easily see the flow and transformation of data in a system. Here are a few tips for using Sankey charts effectively:
- Use clear and concise labeling: Make sure that each node and arrow in the chart is labeled clearly and concisely. This will make it easier for you and others to understand the flow of goods, services, or information in the system.
- Use different colors or patterns for different types of data: In order to make the chart more visually appealing, you can use different colors or patterns for different types of data, such as different types of goods, services, or information. This will allow you to quickly distinguish between different types of data flow.
- Customize the chart to fit your needs: Sankey charts are highly customizable, so you can add or remove nodes and arrows, as well as adjust the appearance of the chart to fit your specific needs.
- Label the nodes and arrows: It is important to label each node and arrow in the chart to make it easy to understand the flow of data. You can use text boxes or arrows to label each node and arrow.
Conclusion
Sankey charts are a powerful visualization tool for understanding the flow and transformation of data in complex systems. They are particularly useful for supply chain networks, financial transactions, and information flows. By following these tips, you can create and use Sankey charts to make sense of your data and improve your understanding of the flow of goods, services, or information in your system.
