[udig-devel] A unique colour for each Feature

[Jody Garnett]

As you can see Andrea - we are in the realm of art and communication :-)

You are correct Paul (and yes I looked at the map).
- pale colours used
- colours assigned spatially so that no two regions that touch have the 
same colour
- border is thickened up with a bolder version of the same colour (to 
make differences apparent)

I recall reading about this cartographic problem somewhere - it was an 
exercise in graph theory.
Fun stuff, but now back to work.
