Data visualization has become an essential tool for professionals working with large and complex datasets. Sankey charts, a type of data visualization that depicts the flow of information between different entities, have gained popularity in recent years. In this article, we’ll explore the basics of Sankey charts and provide tips for creating effective visualization.
What Are Sankey Charts?
Sankey charts are a data visualization method used to show the flow of information or data. Unlike traditional bar charts and pie charts, which show the proportion of a total amount or the percentage of a particular size, Sankey charts convey the direction and amount of flow.
