library(bcdata)
library(ggplot2)Use bcdc_get_data() to get an entire dataset. I wouldn't recommend this
for really large datasets like the FWA:
bcdc_get_data("bc-airports")

the server and only return a subset of the dataset.
We mimic the dbplyr workflow in that the request isn't actually sent
until collect() is called:
