Geocoded cities

The gmaps_cities data frame contains the results of geocoding five cities (“Houston”, “Washington”, “New York”, “Chicago”, “Arlington”) using the Google Maps API on 2022-06-08. The geocoding data appears in the json list-column.

gmaps_cities
#> # A tibble: 5 × 2
#>   city       json            
#>   <chr>      <list>          
#> 1 Houston    <named list [2]>
#> 2 Washington <named list [2]>
#> 3 New York   <named list [2]>
#> 4 Chicago    <named list [2]>
#> 5 Arlington  <named list [2]>

Two cities, Washington and Arlington, were deliberately picked for their ambiguity: Washington could refer to the city or the state, and Arlington could mean the one in Virginia or the one in Texas. This dataset is useful for exploring the rectangling capabilities of the tidyr package.
