The Ultimate Guide to Mastering Sankey Charts: Unleashing the Power of Data Visualization
Sankey charts, also known as node link diagrams, are a type of data visualization that can be used to show the flow of materials, documents, or information between entities. They are a powerful tool that can help you gain insights into data and identify trends and patterns that might otherwise go unnoticed. In this guide, we’ll go over everything you need to know to master Sankey charts, including how to create them, apply them to different situations, and get the most out of the data they represent.
What Are Sankey Charts?
Sankey charts are graphical representations of the flow of materials, documents, or information between entities. The chart consists of nodes (also known as links or boxes) that represent the entities, and edges that connect the nodes and represent the flow of the data. Sankey charts can be used to show a wide variety of data, including the flow of chemicals, pollutants, money, or ideas.
One of the things that sets Sankey charts apart from other types of data visualizations is that they can represent complex, multi-directional flows. This makes them ideal for showing data that has multiple inputs and outputs, such as a supply chain or a complex research project.
Sankey Chart Creation
There are a number of software programs that you can use to create Sankey charts, including Microsoft Excel, Google Sheets, and Lucidchart. Each of these programs has its own unique strengths and weaknesses, so it’s a good idea to try out a few different options to see which one works best for you.
One thing to keep in mind when creating a Sankey chart is the importance of accuracy. Sankey charts rely on the data you input to be correct, so it’s important to make sure that your data is complete and accurate before creating your chart.
Sankey Chart Applications
Sankey charts are a flexible data visualization tool that can be used in a wide variety of situations. Here are a few examples of how you might use Sankey charts:
- Supply chain management: Sankey charts can be used to show the flow of materials or information through a supply chain, allowing you to see where bottlenecks or inefficiencies might exist.
- Academic research: Sankey charts can be used to show the flow of ideas or information between researchers, making it easier to track down the sources of a particular idea.
- Marketing and advertising: Sankey charts can be used to show the flow of customers or prospects through a marketing or sales funnel, allowing you to see which steps are most effective in moving people through the process.
Getting the Most Out of Sankey Charts
One of the keys to getting the most out of Sankey charts is to use them to answer specific questions or explore specific areas of interest. This might involve looking at data from multiple time periods, comparing different entities or processes, or examining the flow of data between different types of nodes.
Another important aspect of using Sankey charts effectively is to keep in mind the overall context of the data. This might involve considering the business or research context of the data, or understanding how the data fits into a broader framework or ecosystem.
Conclusion
Sankey charts are a powerful data visualization tool that can be used to show the flow of materials, documents, or information between entities. They are flexible, accurate, and can be applied to a wide variety of situations, making them a valuable asset for researchers, supply chain managers, marketers, and others.
