This page aims to describe how to realise a basic circle packing chart with only one level of hierarchy. Basically, you just represent each entity or individual of your dataset with a circle, its size depends of a provided value.

 

It is like a barplot, but you use circle size instead of bar length. It is close to a bubble plot, but X and Y position do not mean anything. It is a circle version of a treemap.

 

Calculating the arrangement of dots is not a trivial problem. To resolve it, we use the packcircles library that will calculate the coordinates of every points of the circle edges. Then, we use ggplot2 to plot these shapes!
