Flightpath mapper for Blot (Hackclub).
Inspired by Langlands and Bell (http://www.langlandsandbell.com/portfolio-item/air-routes-of-the-world-night-day-2002/)
Airport DB sourced from OpenFlights (openflights.org).
Due to editor limitations, the script for generating the polylines from airport lists and the script for actually drawing those polylines are separate.
