Sankey charts are a powerful tool for displaying the flow of data and relationships between different categories. These diagrams can be used to illustrate how different processes or inputs are linked to outputs or results. They are often used in fields such as economics, management, and social sciences, where data flows and interrelationships between categories can be represented visually.
Creating a Sankey chart is a simple process that can be done using any computer. Once you have analyzed the data and identified the relationships between categories, you can start plotting the flow and connections between them. In this article, we will guide you through the process of creating a Sankey chart and some applications it can be used in.
Tools and Appropriate Software
Sankey charts are most commonly created in Microsoft Excel using one of its tools, the Excel Pivot Chart. You can also use various software such as Tableau, Power BI, or even hand-drawn diagrams.
When creating Sankey charts, you will need to identify your data categories and the connections between them. Once you have done this, you can start plotting the data using the Sankey chart tool in your chosen software.
