Title: Sankey Chart Creation and Applications: A step-by-step guide

In a recent study titled “Visualization of Complex Data”, researchers have found that using Sankey charts is one of the most effective ways to visualize complex data sets. Sankey charts are a type of diagram that is similar to a flow diagram, which is well-suited for visualizing the relationships between different entities or processes. In this article, we will take you through the step-by-step process of creating Sankey charts and their applications.

Step 1: Understand the Data
Before creating any chart, it is important to understand the data you’re working with. Identify the entities and relationships that need to be visualized on the chart. Sankey charts are best used for describing the relative size of an entity and the flow of information or processes between it and other entities.

Step 2: Determine the Structure of the Chart
Once you’ve identified the entities and relationships, determine the structure of the Sankey chart. The chart should be labeled with the entities and their descriptions, as well as the flow of information or processes they participate in. You can use a combination of colors and shapes to distinguish between different entities or processes.

Step 3: Calculate the Flow Rates
Calculate the flow rates for each entity that participates in the flow of data. This will help you determine the size of the entities and the direction of the flow of information. You can use mathematical equations or charts to determine the flow rates.

Step 4: Design the Chart
Design the Sankey chart by placing the entities along a horizontal axis and the direction of flow along the vertical axis. Choose the appropriate colors and shapes to represent each entity and the flow of data. The flow will be portrayed as a series of arrows between the entities.

Step 5: Display the Results
Finally, display the results by annotating the chart with labels and explanations. Use annotations to label each entity, arrow, and flow rate, and to explain the flow of information or processes.

Applications of Sankey Charts
Sankey charts have a wide range of applications in various fields such as:

• Business and finance: Sankey charts can be used to visualize transactions between a company and its suppliers, customers, and employees, giving a clear picture of the flow of information and resources through the organization.

• Social sciences: Sankey charts can be used to visualize political alliances, social networks, and interactions among individuals.

• Environmental science: Sankey charts can be used to visualize water flow, oil flow, or other chemical substances through a network, making it easier to understand the sources and destinations of these substances.

Conclusion
Sankey charts are an excellent way to visualize complex data sets, thanks to their ability to clearly show flow rates and relationships between entities or processes. By using this guide, you can create a Sankey chart to help you visualize and understand the data you’re working with. With careful planning and attention to detail, Sankey charts can be used to reveal insights and provide valuable information.
