Sankey charts have been called one of the most versatile and effective visualization methods for understanding networks and processes. These charts, which were first created in 2007 by Dr. David F. Wormald of the School of Engineering at the University of Southern California, combine network, flow, and process diagrams in a single chart to present complex data in a clear, concise way. In this article, we will explore the creation and applications of Sankey charts and how they are revolutionizing the way we understand networks and processes.
What is a Sankey Chart?
A Sankey chart is a network visualization tool that uses a network representation of the data along with flow and processes to present the information in a clear and easy-to-understand format. It is a three-dimensional diagram that combines the three main components of a network diagram – nodes, links, and arrows representing flow, to present a comprehensive view.
How to Create a Sankey Chart
A Sankey chart is created using the following steps:

1. Design the network: Define the data you want to visualize and design a network representation of the network. You can use a network diagram tool like Gephi or Visio to create the network.
2. Define the flows and processes: Identify the different flows and processes being used in your network and assign them to the corresponding nodes.
3. Draw the nodes and links: Use the network representation tool to draw the nodes and links according to the data you have defined.
4. Add arrows and flows: Draw the arrows between the nodes and assign the appropriate flows to each.
5. Add information: Add information about the data being visualized, such as labels or annotations.
6. Customize the chart: Customize the chart by adjusting the size, color, and style of the nodes, arrows, and links.

Applications of Sankey Charts
Sankey charts can be used in a wide range of applications that require the insight and understanding of network and process dynamics. These include:

• Engineering: In engineering, Sankey charts can be used to visualize the relationship between different components of a system, including hydraulic, electrical, and pipeline systems.
• Natural sciences: Sankey charts can be used in natural sciences to visualize the processes and flow of information between different elements.
• Business and economics: Sankey charts can be used in business and economics to visualize the processes and flow in supply chains, manufacturing, and logistics.
• Medical: Sankey charts can be used in medical to visualize the flow of information between different elements in a patient’s medical system, such as different departments or different components of a treatment.

Why Sankey Charts Are Revolutionizing the Way We Understand Networks and Processes
Sankey charts are revolutionizing the way we understand networks and processes because they offer a unique insight into complex data. They combine different types of data and provide a clear and intuitive visualization that is easy to understand. Additionally, Sankey charts are easy to customize and can be used to present a wide range of information. This makes them a powerful tool for understanding networks and processes, and a valuable addition to any visualization toolbox.
