Summary
In this chapter we created a new Rails app for flight departures. We loaded three new data files using both Ruby’s CSV library and a custom import rake task. We learned about formatting options with Ruby’s CSV library and also the Matrix class from Ruby’s standard library. Finally, we drew two chord diagrams to look at the relationships between airports.
