A statebins-style equal-area tile grid of the world (one square per country)
so tiny states are actually visible. Uses the bundled world_tiles layout.
For small multiples of a tile grid, facet the result as you would any other
ggplot (or see facet_map() for the choropleth equivalent).
Details
Every tile in the layout is drawn, taking the scale's na.value fill where
data has no row for it. The converse also holds and is quieter: data rows
keyed on one of the 10 countries with no tile are dropped without a warning
(see world_tiles for which).
Examples
# \donttest{
tile_map(countryatlas::world_snapshot$countries, gdp_per_capita)
# }
