Use of graticules
From st_graticule
:
"In cartographic visualization, the use of graticules is not advised, unless
the graphical output will be used for measurement or navigation, or the
direction of North is important for the interpretation of the content, or
the content is intended to display distortions and artifacts created by
projection. Unnecessary use of graticules only adds visual clutter but
little relevant information. Use of coastlines, administrative boundaries
or place names permits most viewers of the output to orient themselves
better than a graticule."
