Symbolizing polygons

[Doug Nebert]

I wish to serve a map which, for example sake, will illustrate
several classes of polygon as red, yellow, and green (for example
sake) creating a choropleth map based on an attribute in the 
associated table. 

Can someone point me to a nice example where this is done so I
can see what the map file would look like? I believe I will need
to regenerate the map file when the attributes change, yes?

Doug.
