The visualization reflects data directly from the GTFS feed. Route paths, stops, colors, and labels are all derived from the feed files (routes.txt, trips.txt, stop_times.txt, stops.txt, and shapes.txt where it's defined). If a route doesn't specify a color, it appears in black. When multiple shapes exist for different trips on the same route, they're combined into one for display.
