For 2-d views v.thematic in the 6.1 works for this nicely. Michael Barton posted an update to the d.m for 6.1 and it is included in there. I can't recall if it is in the current cvs d.m or not. It isn't in available in 6.0. As per 3-d views, I can't get nviz to function properly in 6.1 so I can't say, but AFAIK, that capability isn't available in 6.0 (at least not through the tk interface).
