What kind of circles are you looking for? If you just want small
circles to mark point locations, then make a .png and use a
PointSymbolizer with it. But if you're trying to vary the size of the
circles, like for example "draw me a circle where the radius is
proportional to the population of the town", then you'd be better off
creating polylines in postgis (or shapefile) and then just
LineSymbolizer / PolygonSymbolizer depending on whether you want the
outline or it filled.
Cheers,
Andy
