I see you highlight that, but I believe the visualization is designed to be intuitive once you interact with it a bit—no legend stricty needed if you calibrate against what you already know.

Pick a flight you know (maybe one near yer home) and play with the options -- what patterns emerge? Red draws attention, “Boeing vs. Airbus” compares data, while “Altitude & Velocity” combines them. Explore hands-on; discovery often makes insights click better than instructions.
