Data visualization is the process of presenting information, data or facts in a visual format. This can be done in many ways such as using charts, graphs, maps, and tables. In this article, we will be focusing on Sankey charts and how to create and apply them.
What is a Sankey Chart?
Sankey charts are a form of flow chart that are used to present data in an easy-to-understand manner. They are also known as “transfer” or “channel” charts, with “sankey” being the word for the vertical lines that connect the ports with the data to show how the information is flowing between the entities or processes involved.
How to Create a Sankey Chart
Creating a Sankey chart requires some basic knowledge about data flow and the different symbols and labels used in the chart. The following steps will outline the basic steps to create a Sankey chart:
Step 1: Set the Data Flow

• Start by determining the data flow that you want to represent. This can be done by creating a table containing all of the relevant information.
• Use arrows to represent each flow. Arrow tips should be used to indicate the direction of each flow and indicate the quantity of information that passes through.
• Use lines to connect the ports. The colors and thickness of the lines can help identify the source and destination ports and can indicate the type of information that passes through.

• Add labels to the arrow tips and the lines to provide additional information.
  Step 2: Label the Ports and Lines

• Assign a unique number or symbol to each port. This will make it easy to identify each port in the chart.

• Use the text labels that come with the software or write the name of each port in the chart.

• Use symbols to represent the data that is passing through each port. This can be done by using the various symbols that are available in the software.
  Step 3: Create the Sankey Chart

• Start by drawing a chart with the correct dimensions and orientation.

• In the chart, position the ports and arrows to represent the data flow.
• Use the lines to connect the ports and the arrows to connect the flow.
• Use the text labels and symbols to provide additional information and make the chart easy to understand.

Examples of Sankey Charts
There are many different types of Sankey charts that can be used to represent different types of data and different types of information. Here are some examples of Sankey charts:

1. Sankey charts that represent the flow of information in a business or organization.
2. Sankey charts that represent the flow of resources in a project or building
3. Sankey charts that represent the flow of data in the health sector.
4. Sankey charts that represent the flow of energy in the natural world.

Conclusion
When using Sankey charts, it is important to remember that these charts are helpful for presenting data in a visual format. They can help explain complex data flows and can make it easier to understand. However, it is important to use Sankey charts wisely to make sure they are effective and appropriate for the purpose being served.
