Examples

# lower 48 states only
ggplot(US_states_geoms$lower48) + geom_sf(fill = "#56B4E9", color = "grey30", size = 0.3, alpha = 0.5)

# true Albers projection, with AK and HI in their correct locations
ggplot(US_states_geoms$true_albers) + geom_sf(fill = "#56B4E9", color = "grey30", size = 0.3, alpha = 0.5)

# standard US Albers map, with AK artificially small
ggplot(US_states_geoms$us_albers) + geom_sf(fill = "#56B4E9", color = "grey30", size = 0.3, alpha = 0.5)

# revised US Albers map, with AK at its original size
ggplot(US_states_geoms$albers_revised) + geom_sf(fill = "#56B4E9", color = "grey30", size = 0.3, alpha = 0.5)

# County and state boundaries overlaid
ggplot(US_counties_geoms$albers_revised) + 
  geom_sf(size = 0.3) +
  geom_sf(data = US_states_geoms$albers_revised, fill = NA, color = "red")
