Visualising the Taxi Times

I've created a quick Tableau Public story to show and explain some of the CODA taxi time data (see previous blog post).

Since I last looked, Tableau have added in-built support for airport codes as geocodes, so mapping is just getting easier. But I still find I can't decide whether to stick to tidy data (in the R tidyverse sense: one value per row) or have more columns; there seem to be graphs in Tableau that I can draw with one and not the other, or vice versa.
