Welcome to AlgebraOfGraphics! ​

AlgebraOfGraphics (AoG) defines a language for data visualization, inspired by the grammar-of-graphics system made popular by the R library ggplot2. It is based on the plotting package Makie.jl which means that most capabilities of Makie are available, and AoG plots can be freely composed with normal Makie figures.

Example ​

In AlgebraOfGraphics, a few simple building blocks can be combined using + and * to quickly create complex visualizations, like this:

using AlgebraOfGraphics, CairoMakie

spec =
    data(AlgebraOfGraphics.penguins()) *
    mapping(
        :bill_length_mm => "Bill length (mm)",
        :bill_depth_mm => "Bill depth (mm)",
        color = :species => "Species",
        row = :sex,
        col = :island,
    ) *
    (visual(Scatter, alpha = 0.3) + linear())

draw(spec)

Installation ​

You can install AlgebraOfGraphics from the General Registry with the usual Pkg commands:

using Pkg
Pkg.add("AlgebraOfGraphics")
