What is the ggplot2 package?

In this section, we’ll delve into the fundamental aspects and key features of the package.

ggplot2 is a widely-used package for creating high-quality static graphics. It implements the grammar of graphics, an easy-to-understand system for building plots, and comes with a variety of geoms, stats, scales, and themes that allow for extensive customization.

Title: Create Elegant Data Visualisations Using the Grammar of Graphics
Description: A system for 'declaratively' creating graphics, based on "The Grammar of Graphics". You provide the data, tell 'ggplot2' how to map variables to aesthetics, what graphical primitives to use, and it takes care of the details.
