Maps with ggplot2: Plotting Geospatial Data

The beauty of ggplot2 is that it treats geographic shapes just like any other aesthetic mapping. By using the specialized geom_sf() layer, you can turn spatial data objects into beautiful, layered maps with the same "grammar" you already know.

In this lesson, you’ll learn how to visualize spatial data by plotting polygons, points, and lines. We’ll cover how to map variables to fill colors to create choropleth maps, handle multiple spatial layers on a single canvas, and how to change the projection of your map.
