Sankey charts are a powerful visualization tool that can help you understand the flow of information or resources between different components in a system. In this article, we will explore the secrets of creating a successful Sankey chart and how to effectively use this data visualization method to gain insights about your system.
Before we dive into the creation of Sankey charts, it’s important to understand the concept behind them. Sankey charts are a diagrammatic representation of the flow of resources, typically used to communicate the flow of information between different sources or sinks in a linear flow. The chart is made up of a set of lines that link the sources and sinks, with arrows indicating the direction of the flow. The width of each line represents the amount of flow, with thicker lines indicating larger amounts of flow.
Creating a Sankey chart requires some specific knowledge and skills. First, you’ll need to gather all of the data you’ll be using to create the chart. This data should include the sources and sinks, as well as any information you want to visualize in the chart. Next, you’ll need to create a schematic diagram that visually represents the flow of data or resources, with the sources and sinks shown as different colors or symbols on the diagram.
Once you have the data and a schematic diagram, you can start the actual creation of your Sankey chart. This can be done with a software program, such as Microsoft Power BI or Tableau, or with specialized software designed for creating Sankey charts, such as R or Python.
In terms of applications, Sankey charts are commonly used in data science and engineering, as well as in project management and business analytics. For example, in project management, Sankey charts can be used to visualize the flow of resources between tasks or stakeholders. In data science, Sankey charts can be used to visualize the flow of information between different data sources or sinks. In business analytics, Sankey charts can be used to visualize the flow of resources between different departments or regions within a company.
To create a successful Sankey chart, it’s important to keep the following tips in mind:
1. Keep it simple. The complexity of the chart can make it difficult to understand the flow of information.
2. Use clear and concise labels. Make sure you label each line accurately and clearly.
3. Use different colors or symbols to represent different sources or sinks.
4. Use labels or legends to indicate the flow direction and the significance of each component.
5. Test and retest your chart. It’s not uncommon for people to make mistakes when creating Sankey charts, so make sure you double-check your work before presenting it to others.
In conclusion, Sankey charts are a powerful data visualization tool that can help you gain insights about the flow of information or resources in your system. By following the tips outlined above and using the right software, you can create a successful Sankey chart that effectively communicates the flow of information between different components.
