Abstract: Most plotting packages offer a fixed set of built-in plot types to choose from. In contrast, the Grammar of Graphics defines a declarative framework for creating virtually unlimited visualizations by combining geometry, coordinate systems, facets, scales, guides, and themes. The most widely known implementation of this grammar is R's ggplot2, with a lesser-known Python counterpart called plotnine. This presentation introduces both libraries and demonstrates how the Grammar of Graphics can be used to build a wide range of plots.
