Sankey charts are a powerful tool for visualizing complex data sets. These charts were first introduced in the late 1800s to aid in the study of hydraulic systems, but today they are used in a wide variety of fields including finance, engineering, and social sciences.
Sankey charts, also known as directed flow graphs, are a type of flowchart where the size of each node represents the quantity of a resource (such as money in a business model, or airflow in a hydraulic system), while the length of each line represents the relationship between two nodes or the direction of flow between two nodes.
In this article, we will explore the secrets of creating and using sankey charts to better understand the underlying data and visualize it in a clear and concise manner. Here are some key tips and principles to keep in mind when working with sankey charts:
1. Choosing the Right Tools and Resources
To create a sankey chart, you will need to use a software or application that supports the creation of flowcharts and directed flow graphs. Some popular options include the free software Gephi, which has a user-friendly interface and a wide range of customization options. Other options include Microsoft Excel, ArcGIS, and others that offer similar visualization capabilities.
2. Understanding the Basics of Sankey Chart Creation
To create a sankey chart, you will first need to define the flow direction (upstream or downstream), the quantity or resource represented by each node (such as money or airflow), and the length of each line representing the flow between two nodes. You will also need to ensure that the order of the nodes and lines is consistent between your input data and your sankey chart visualization.
3. Visualizing Complex Data with Sankey Charts
Once you have defined the components of your sankey chart, the next step is to visualize the data. You can do this by adding color to the nodes to represent the quantity of the resource (such as the amount of money in your financial model), using different colors or styles to represent the flow direction (upstream or downstream), and applying other formatting options to make the chart more visually appealing.
4. Using Sankey Charts for Analytical Analysis
Sankey charts can be used in a variety of analytical scenarios, including understanding the flow of resources in a business model, analyzing the flow of money in a financial model, or investigating the flow of information between different groups or entities. By breaking down complex data sets into easily digestible flow charts, sankey charts can make it easier to see the relationships and patterns underlying the data.
5. Applying Sankey Charts to Real-World Applications
Sankey charts are not just limited to finance and business. They can also be used in a wide range of real-world applications, including engineering analysis, social sciences, and public policy. For example, in engineering, sankey charts can be used to visualize the flow of materials and energy through a complex system, while in social sciences, they can be used to analyze the flow of ideas and information within a community or organization.
In conclusion, sankey charts are a valuable tool for visualizing complex data sets. By understanding the basics of sankey chart creation, visualizing the data, and applying them to real-world scenarios, you can gain a deeper understanding of your data and make more informed decisions based on the information you have. So take some time to explore the world of sankey charts, and see the power they have to change how you view and interact with data.
