Sankey charts have become increasingly popular in recent years as a powerful visualization tool for presenting complex data. These intuitive charts are easy to understand, making them ideal for communicating information to non-experts. In addition to their simplicity, sankey charts can be used to visualize a wide range of data types, including flow diagrams, network diagrams, and decision trees.
In this article, we’ll explore the concept of sankey charts and how they work. We’ll also discuss some of the key benefits of using sankey charts in data visualization. Finally, we’ll provide some tips and best practices for ensuring that your sankey chart is both clear and compelling.
What Are Sankey Charts?
Sankey charts are a type of diagram that uses flow lines to show how different parts of a system (such as a graph or network) interact with each other. The diagram consists of a set of nodes, which represent the elements of the system, connected by flow lines that represent the flow of information or resources between those elements. The flow lines are drawn in a specific direction, usually from the source node to the sink node.
Sankey charts can be used to visualize a wide range of data types, including flow diagrams, network diagrams, and decision trees. In the context of data visualization, they are often used to summarize complex data as a flow from source to sink, with arrows pointing to show the direction of the flow. This allows users to quickly understand the overall flow of information or resources within a system.
Benefits of Using Sankey Charts
Sankey charts offer several benefits for data visualization, making them an ideal tool for presenting complex data. Here are some of the key benefits of using sankey charts:
1. Simplicity: Sankey charts are simple to create and understand, making them ideal for non-experts. The diagram is made up of a set of nodes and edges, with each edge connecting two elements of the system. This makes it easy to understand the overall flow of information or resources within a system.
2. Clear and compelling visualizations: Sankey charts are an effective tool for visualizing complex data. The flow lines are easy to read and understand, making it easy to see how information or resources are flow between different elements of a system. This makes sankey charts particularly appealing to a diverse set of users, from business analysts to non-technical stakeholders.
3. Comprehensive data visualization: Sankey charts are an effective way for businesses, organizations, and individuals to summarize complex data as a flow from source to sink. This allows users to quickly understand the overall flow of information or resources within a system, making it easier to make data-driven decisions.
Creating a Sankey Chart
Creating a sankey chart is a relatively straightforward process. Here’s a step-by-step guide to get you started:
1. Identify the system you want to visualize: Start by identifying the system you want to visualize. This could be a flow diagram, network diagram, or decision tree, depending on the type of data you want to visualize.
2. List the elements of the system: Once you’ve identified the system you want to visualize, start by listing the different elements of the system. Be sure to include the source and sink nodes, as well as the flow lines that represent the flow of information or resources between those elements.
3. Create the flow lines: Now it’s time to create the flow lines. These lines will represent the flow of information or resources between the different elements of the system. Be sure to mark each flow line with the direction of flow.
4. Add the nodes: Finally, add the nodes to the diagram. These will represent the different elements of the system and their corresponding flow lines.
Tools for Creating Sankey Charts
Creating a sankey chart can also involve using specialized data visualization tools. Some popular tools for creating sankey charts include Lucidchart, Draw.io, and MS Visio.
In conclusion, sankey charts are a powerful tool for visualizing complex data and summarizing it as a flow from source to sink. By following these steps and using the right tools, you can create visually compelling sankey charts that make your data more accessible and easier to understand.
