I would like to create a graph that indicates Aircraft Departures per unit of
time at the airport. I have access to flight departure times for every
aircraft so my list of data would be something like:

07:00 American
07:06 American
0712 United
0800 Allegiant
10:00 Delta
12:30 Southwest

And so on for a days worth of flights. (Probably 50 or more)

The goal is to graphically show what hours of the day have the most
activity. In my example my chart would indicate the time period around 07:00
in the morning has more departure activity than 12:00 Noon.

Any suggestions on how to proceed?
