Sankey diagrams are a type of visual data mapping that displays information flowing through a network or process. They are a powerful tool for presenting complex relationships between different variables and components of a system. In this article, we will explore the power of Sankey charts and how they can help you understand the flow of data in a more efficient way.
What are Sankey Charts?
Sankey charts are a type of network graph that visualize the flow of data, such as people, money, or information. They are created by placing nodes (points) in a diagram that represent different elements of the system, and connecting them with lines that show the flow of data through them. The number and type of nodes and lines can vary, depending on the specific context of the data you are mapping.
Applications of Sankey Charts
Sankey charts can be used in many different scenarios, and their applications often depend on the type of data you are working with and the context of the system you are mapping. Here are some examples of common use cases:
1. Process mapping: Sankey charts can be used to visualize process flows, such as the flow of people through a company, or the flow of information through a project.
2. Economic mapping: Sankey charts can be used to visualize the flow of resources, such as money or labor, in an economy.
3. Network mapping: Sankey charts can be used to visualize the flow of information or data within a network of relationships, such as the flow of traffic patterns or the flow of messages between stakeholders in a project team.
4. Political processes: Sankey charts can be used to visualize the flow of information and resources within a political system, such as the flow of money to different political campaigns.
Creating a Sankey Chart
Creating a Sankey chart involves several steps:
1. Identify the elements: The first step is to identify the elements of the system you want to visualize. These can be different types of flow, such as the flow of people or information, or different types of nodes, such as different types of organizations or individuals.
2. Draw the nodes: Add a node for each element of the system. You can either manual create them or use pre-made nodes.
3. Draw the lines: Draw lines between nodes to represent the flow of data. These lines can be thick or thin, depending on the amount of data being passed through the system.
4. Use color and symbols: Sankey charts can be used to visually differentiate the flow of data, and different types of nodes can be distinguished using different colors or symbols. This can help to make the chart more visually appealing and easier to understand.
5. Check the chart: Before creating your final Sankey chart, make sure it makes sense and accurately reflects the relationship between the elements you have identified.
Conclusion
Sankey charts are a powerful tool for visualizing the flow of data in a system. By understanding how to create and use Sankey charts, you can gain a deeper understanding of the data you are working with and make data-driven decisions. Whether you are mapping out the flow of people, money, or information in an organization, or visualizing the flow of resources in an economy, Sankey charts can help you to make sense of the relationships in your data.
