This is how I've visualized OpenStreetMap's node density.

download the source data

 wget http://fred.dev.openstreetmap.org/density/tiles.13
 wget http://fred.dev.openstreetmap.org/density/tiles.16

convert to simple, gnuplot-readable text format

 sed 's/\([0-9]*\) z=\([0-9]*\) x=\([0-9]*\) y=\([0-9]*\)/\3 \4 \1/' < tiles.13 > tiles.13.txt
 sed 's/\([0-9]*\) z=\([0-9]*\) x=\([0-9]*\) y=\([0-9]*\)/\3 \4 \1/' < tiles.16 > tiles.16.txt
