 - Note that, although `ggplot` automatically reprojects vector data when plotting multiple shapefiles with
   different projections together, it is still important to be aware of the CRSs of your data and to keep track
   of how they are being transformed.

   the syntax explained.
 - This is the first instance of a faceted plot in this workshop.
