Image Resolution using Algebra of Graphics [Makie]

Hi,

How can I improve the quality of the figures of the Algebra of Graphics on Pluto? The quality of the output figures on my Laptop was very low (resolution problems ?; my laptop has a 4K display) when compared with the figures presented in this tutorial (Tutorial 🐧 · Algebra of Graphics). I use the same code but with a different dataset.

using AlgebraOfGraphics, CairoMakie

set_aog_theme!()

axis = (width = 225, height = 225)
penguin_frequency = data(penguins) * frequency() * mapping(:species)

draw(penguin_frequency; axis)

You can also do

CairoMakie.activate!(; px_per_unit=4)
