Sankey charts are a type of flowchart that are used to visualize the flow of a system or process. They are particularly useful for understanding complex systems and showing the interconnections between different parts of a system. In this article, we will explore the basics of Sankey chart creation and some of the ways in which these charts can be used to gain insights into complex systems.
What is a Sankey Chart?
A Sankey chart is a type of flowchart that is used to visualize the flow of a system or process. It is named after the Dutch engineer and economist Jan de Vries Sankey, who developed the chart in the 1870s. The chart consists of a set of interconnected circles, known as nodes, which represent different parts of a system. These nodes are connected by arrows, which represent the flow of a particular substance or information through the system. The chart can be used to show the direction and magnitude of this flow, as well as to identify bottlenecks and other areas of potential improvement in the system.
Sankey Chart Creation
Sankey charts can be created using a variety of software tools, including Microsoft Excel, Visio, and Adobe Illustrator. These tools provide a range of options for customizing the chart and adding additional information, such as labels and annotations. In addition, many of these tools have libraries of pre-designed Sankey chart templates, which can be used as a starting point for creating new charts.
Applications of Sankey Charts
Sankey charts are particularly useful for understanding complex systems and showing the interconnections between different parts of a system. Some examples of how Sankey charts can be used include:
Improving Supply Chain Management
Sankey charts can be used to visualize the flow of materials and products through a supply chain. This can help identify bottlenecks and areas where Improvements can be made to optimize efficiency and reduce costs. For example, a Sankey chart of a supply chain might show that a particular supplier is a major bottleneck, and efforts could be made to reduce the time it takes for goods to travel from that supplier to customers.
Managing Information Systems
Sankey charts can also be used to visualize the flow of information through an organization or system. This can help identify areas where data is lost or corrupted, and allow IT departments to take steps to improve data quality and efficiency. For example, a Sankey chart of an information system might show that a particular file or database is a major bottleneck, and efforts could be made to update the system to improve efficiency.
Analyzing Environmental Systems
Sankey charts are also used in Environmental science to visualize the flow of energy, matter and pollutants through ecosystems. This can help identify areas where pollution or resource depletion occurs, and allow scientists to develop strategies to alleviate these problems. For example, a Sankey chart of an ecosystem might show that a particular pollutant is flowing into a food web, and efforts could be made to reduce its inputs to the system.
Conclusion
Sankey charts are a powerful visualization tool for understanding complex systems and identifying areas where improvements can be made. Whether you are working on a supply chain, information system, or environmental system, Sankey charts can help you gain a deeper understanding of the flow of materials, information, and pollutants through your system. With the right tools and resources, you can easily create Sankey charts to help you understand and improve your systems.
