I have imported a shape file of polygons representing canadian provinces. I also have a list of projects that have a particular dollar value attributed to them.
I would like to create a map that can classify each province by totla dolar value of all projects. Each classification would have a dollar range associated with a color.
Alternative would be to do pie charts or other graphics to easily examplify the distribution of money amongst provinces.
I am thinking that I have to link the GRASS data with a postgres table.
I looked in the GRASS book (2nd ed) and thorugh the wiki and man pages. No hints.

David, linking to postgres can be useful, but you can accomplish what you are trying to do using the
default GRASS database.
Would I just build onto the existing table or create a separate table and again link them?
I will eventually want to information accessible through WMS and perhaps other applications hitting the DB. but this might be a good proof of concept for right now.
