ggmap

Maps are plotted as ggplot2 layers, enabling full use of geoms, stats, and faceting, as shown in examples with geom_point and facet_wrap for layered visualizations.

Functions like get_stadiamap and get_googlemap fetch raster tiles from Google, Stadia, and OpenStreetMap, simplifying background map addition without manual HTTP requests.

The qmplot() function automatically computes bounding boxes for scatterplots on maps, reducing setup time, as demonstrated in the violent crime data example.

Includes geocode() and revgeocode() for address lookup using Google's API, with mutate_geocode for dplyr-style workflows, enhancing spatial data preparation.

Supports various map types like terrain, satellite, and hybrid from multiple providers, allowing customized aesthetics as shown in the Stadia Maps and Google Maps examples.
