Visualize your data using a few simple building blocks that can be composed using + and *. AlgebraOfGraphics puts a new algebraic spin on the grammar of graphics idea known from R’s ggplot2 package.

Visualizations are powered by Makie and you have its full capabilities available to tweak figures produced by AlgebraOfGraphics.

Example

using AlgebraOfGraphics, CairoMakie

penguins = AlgebraOfGraphics.penguins()

set_aog_theme!()
update_theme!(Axis = (; width = 150, height = 150))

spec = data(penguins) * mapping(:bill_length_mm, :bill_depth_mm)

draw(spec)

by_color = spec * mapping(color = :species)

draw(by_color)

with_regression = by_color * (linear() + visual(alpha = 0.3))

draw(with_regression)

facetted = with_regression * mapping(col = :sex)

draw(facetted)

draw(facetted, scales(Color = (; palette = :Set1_3)))
