Aviation Crash Atlas – Map of Commercial Airplane Crashes

Upon first glance it appears to be a heat-map of traffic/busy routes.

Is there some way to warp the map to draw out more inferences? E.g. Busy routes shown with thicker lines; crash density with color. So anomalous crashes can be identified at a glance.

As a pilot and map nerd, I thought it would be cool to map out the major crashes, and find some new ones too. Used a coding agent to scrape wikipedia and make the map.
