This data would be pretty helpful for large meshes to understand where the problematic areas of the mesh are.

The initial implementation could be pretty simple. Maybe something like:

Every hour, take the last 24 hours of telemetry packets
Join those packets on the last location of the reporting node
Bucket those packets into 5km x 5km grids
Take the min, max, mean, and median channel utilization / air time as the bucket values
Assign a colors to that bucket roughly tracking the official Meshtastic thresholds for green, yellow, red.

If it turns out to be useful, you could iterate on things like:

Use the nearest position in time to the telemetry packet rather than the last position
Allow selectable time windows and not just last 24 hours
Create zoom-dependent grids for the heat map

Those these changes would probably warrant a switch to a different processing model than the batch, compute everything model.

I started to work on the heat maps.

https://meshview.bayme.sh/heatmap.html, Need to also do packet and then find a way to incorporate it into the current site.
