I hereby acknowledge that Plots.jl and Makie.jl need more work, it’s currently not easy to make pie plots with them that follow best practices.
There are other options though, like the one given here:
using PyPlot
pie([15,15,30,60], explode=[0,0.3,0,0], labels=["A","B","C","D"],
autopct="%1.1f%%", shadow=true, startangle=90)
