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.
