How to Make Alluvial Diagrams
Here’s how to do it in R from start to finish, plus editing in illustration software. Make design choices and trade-offs for more readable charts.
An alluvial diagram is a type of flow chart that is useful to show change over time. You see how individual categories and how the composition of the categories shift.
In this tutorial, I describe not only how to make a basic chart, but how you get from raw data all the way through the design process, to clear and readable graphics, and to the finished project.
Chart generation is the easy part. Everything before and after is what makes the charts better.
