Sankey charts are a type of flowchart that is used to visualize the flow of data or energy between different entities or regions. They are also known as directed acyclic graphs (DAGs) and are a powerful tool for understanding and analyzing complex systems. In this article, we will explore the basics of Sankey chart creation, as well as some of the many applications of these charts in fields such as engineering, finance, and sustainability.

Sankey Chart Creation

Sankey charts can be created using a variety of software tools, including Microsoft Excel, Lucidchart, and SmartDraw. These tools typically offer a range of features for creating and customizing Sankey charts, such as the ability to add and remove nodes and directed lines, as well as the ability to set node and line properties such as colors and text.

To create a Sankey chart, you will need to have some basic information about the system you want to visualize. This may include the names of different entities or regions, as well as information about the flows of data or energy between these entities. This information can be used to create a directed acyclic graph (DAG) that represents the flow of data or energy, with nodes representing entities or regions and directed lines representing the flow of data or energy between these nodes.

Sankey Chart Applications

Sankey charts are a powerful tool for visualizing and analyzing complex systems, and have a wide range of applications in fields such as engineering, finance, and sustainability.

In engineering, Sankey charts are often used to visualize the flow of materials or energy through a system, helping engineers to identify potential bottlenecks or areas for optimization. For example, a Sankey chart might be used to visualize the flow of water through a city’s infrastructure, helping engineers to identify areas where water conservation measures might be implemented.

In finance, Sankey charts can be used to visualize the flow of money or assets between different accounts or regions, helping financial analysts to identify potential risks or opportunities. For example, a Sankey chart might be used to visualize the flow of money between different countries, helping analysts to identify patterns and trends that might be of interest.

In sustainability, Sankey charts are often used to visualize the flow of resources or pollutants through a system, helping policymakers to identify areas where resource conservation measures might be implemented. For example, a Sankey chart might be used to visualize the flow of water through an agricultural system, helping policymakers to identify areas where water conservation measures might be implemented to improve overall water efficiency.

Conclusion

Sankey charts are a powerful tool for visualizing and analyzing complex systems, and are widely used in fields such as engineering, finance, and sustainability. By creating and customizing Sankey charts, it is possible to gain valuable insights into the flow of data or energy between different entities or regions, and to identify potential bottlenecks or areas for optimization. Whether you are an engineer, a financial analyst, or a policymaker, Sankey charts can be a valuable resource for understanding complex systems and making informed decisions.
