Sankey charts are a powerful tool for visualizing the flow of information in a network, much like Gantt charts work for visualizing the flow of tasks. However, while Gantt charts show linear paths that flow up and down, Sankey charts show directed paths that flow from one node to another. Here’s an article on how to create and use a Sankey chart to map how informationflows.

What is a Sankey Chart?
A sankey chart is a graphical representation of a network in which you can visually track the flow of information between various sources and destinations. Invented by economist Joseph Sankey in the late 1800s, these charts are often used in economic analysis to show how resources are allocated on a given topic.

How to Create a Sankey Chart
To create a sankey chart, you will need to gather the relevant data and organize it into a network of nodes and links. Here’s a step-by-step guide on how to get started:

1. Collect your data: Collect the relevant data on the information you want to visualize. This could include information about sources and topics, topics and destinations, and the flow of information between them.
2. Draw your network: Use a network layout software or tool to draw your network of nodes and links. Start with the sources (or areas of interest), then add the topics or destinations, and finally connect them with links.
3. Calculate the flow of information: Once the links have been drawn, work out the total flow of information between each pair of nodes. This can be done manually by labeling the links with the flow rate, or using software that automatically calculates the flow based on the links drawn.
4. Add labels and text: The labels and text on your sankey chart are essential in helping understand the data you’ve collected. Include labels on the nodes, topics, and links to give the reader a clear understanding of the information you’re visualizing.
5. Present your chart: Once you’ve created your sankey chart, it’s time to present it to the reader. Use the chart as a visual tool to help explain the information you’ve gathered and help clarify the flow of information between the different sources and destinations.

Using Sankey Charts for Information Flow Mapping
Sankey charts are a fantastic tool for visualizing how information flows between different sources and destinations. They’re incredibly useful for understanding the relationships between different areas of interest and can be used to show how resources are allocated in a particular field, such as politics or economics.

Here are a few key applications of sankey charts:

1. Understanding complex relationships: Sankey charts can help you identify complex relationships between different sources and destinations, making it easier to understand the flow of information.
2. Visualizing multiple topics: Sankey charts can be used to visualize the flow of information from one topic to another, helping you to see how different areas are interconnected.
3. Understanding change: Sankey charts can be used to visualize the change in flow of information over time, helping you to understand how information is being moved and to identify areas of growth.

In conclusion, sankey charts are a powerful tool for visualizing the flow of information in a network. As a result, they can help you to understand complex relationships, visualize multiple topics, and visualize the change in flow of information over time. Sankey charts are an excellent addition to your visual data visualization toolkit and can be a valuable asset in any field or industry that involves information flow analysis.
