Introduction
Sankey charts, also known as flowcharts or directed acyclic graphs, are a type of diagram that illustrate the direction and magnitude of a flow of something, such as materials, money, or information. They are an effective way to visualize complex systems and can help identify bottlenecks and opportunities for improvement. In this article, we will explore the beauty and power of Sankey charts and how they can be used to create informative and useful visualizations.
Sankey Chart Creation
To create a Sankey chart, you will need to gather data on the flow of whatever it is that you want to visualize. This data should include the origin and destination of the flow, as well as the amount or velocity of the flow. You can then use a diagramming tool such as Microsoft Visio, Lucidchart, or draw.io to create the chart.
To start, you will need to create a directed acyclic graph (DAG). This is done by adding nodes to the chart, with each node representing a source or sink of the flow. You will then add edges between the nodes, with the edges indicating the direction of the flow. Finally, you will use the diagramming tool to assign values to the chart, such as the amount or velocity of the flow.
Applications
Sankey charts are a powerful tool for visualizing a wide range of flows, from materials and money to information and ideas. Some of the key applications of Sankey charts include:
- Process flow analysis: Sankey charts are especially useful for visualizing the flow of a process, such as a manufacturing line or a supply chain. By using a Sankey chart, you can easily identify bottlenecks and areas where process improvement is needed.
- Financial analysis: Sankey charts can be used to visualize the flow of money, such as a company’s revenue or expenses. This can help identify areas where cost-cutting or revenue-generating opportunities exist.
- Supply chain management: Sankey charts can be used to visualize the flow of goods and services through a supply chain. This can help identify areas where delays or bottlenecks occur, as well as opportunities for improving efficiency.
- Information visualization: Sankey charts can be used to visualize the flow of information, such as the spread of a rumor or the transfer of knowledge within an organization. This can help identify areas where information is trapped or where it is not being shared effectively.
Conclusion
Sankey charts are a powerful tool for visualizing a wide range of flows and can be used in a variety of applications. By gathering data on the flow of something and using a Sankey chart to visualize it, you can gain insights into complex systems and identify opportunities for improvement. Whether you are analyzing a manufacturing process or visualizing the flow of information within an organization, Sankey charts can help you create informative and useful visualizations.
