A friend of mine made this adsb website with a heatmap, autopilot that shows routes, and a 72 hour timelapse of long-haul traffic. Each triangle is a long-haul flight (>3700km) Note that flights under 300kts are not included in the heatmap as he didn't want it to be too clustered around airports.
The url is globular-adsb.copey.dev He and I would both love if you checked it out. My favorite part is the 72hr timelapse.
