 > **AlgebraOfGraphics.jl** is a high-level plotting library built on top of Makie.jl that provides a declarative algebra for creating complex visualizations, similar to **ggplot2**'s "grammar of graphics" in R. It allows you to construct plots using algebraic operations like **(*)** and **(+)**, making it easy to create sophisticated graphics with minimal code.
