<br>
I'm trying to get my head around Grass (6.4.0) in linux for the
first time, am playing around with a vector polygon map and have
reached my first stumbleblock:<br>
How do I color the polygons by the value of an attribute column
(say population)? When looking in the layer manager window and
clicking on "properties" of my layer,<br>
it looks as if you can set the color based on z height of the
vector map - but how do I tell Grass which attribute column that
is Z?<br>
<br>

In the GUI it's the "Add various vector-based maps" (just to the
right of the "Add vector map" button) and choose "Thematic layer".
In the dialog you can choose which attrib column and what color ramp
to apply.<br>
The CLI command is 'd.vect.thematic'<br>
