We would also like to know which states tend to experience early arrival times. Create a series of maps $($small multiples$),$ one each for a quarter, that visualizes the arrival times that you can expect in each origin state within the continental United States $($the $48$ contiguous states$).$ Colors should range from dark blue for states with early arrivals to dark red for states with late arrivals. Do you observe a trend in flight arrivals over time?
