Someone needs to Tufte-fy this. I don't know if it's the hug of death or not but when I zoom out, I don't see (what I assumed would be) a distribution of deaths, a sort of heatmap of occurences. Then if you add a time dimension with color or some other parameter, it could give us a sense of what areas are most dangerous to avoid. At the moment the pins / tooltips are not very ergonomic and they obscure more than they reveal.
