It exists in the form of Google Earth. Put your data there, and if
things are clustered together GE will take care of it. You can also
use their Level of Detail so that things (dis)appear at a given zoom
level(s).

Thanks David (again!)
Any idea if there are more detailed datasets out there that I can for
example
; Overplot coastline data:
MAP_CONTINENTS, /CITIES, COLOR=black
or some topographic color data so the maps look more professional?
And if the xyouts are too close to each other then the text overlaps.
I imagine writing something to stop this is going to be pretty hard
unless it exists already?
Cheers

Yes. :-)
Map_Set, /Cylindrical, /Continents
XYOUTS, lon, lat, name, ALIGN=0.5
