📊ggplot2

NEW

An R plotting system based on the Grammar of Graphics for building layered visualizations.

DESCRIPTION

ggplot2 provides a declarative system for creating complex plots by mapping data to visual aesthetics and layering geoms, stats, and scales. It encourages a consistent, composable approach to visualization. Integrated with the tidyverse, it supports workflows for exploration and publication-quality figures. Its grammar enables facets, themes, and extensions for specialized charts.
