Hi david,<br><br>thanks for replying on my post. actually we'd like to use it more for describing density in a local area, say at a certain center-point, then try to render a circle of variable radius. does this help enlighten you?<br>
<br>Andy Allan gave this reply in the dev mailing list:<br><br><i><font size="3" face="Times New Roman"><span style="font-size: 12pt; font-style: italic;">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<br>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<br>LineSymbolizer / PolygonSymbolizer depending on whether you want
the outline or it filled.</span></font></i><br><br>although i wonder how exactly to implement this? we currently tried installing a local osm, and pre-render tiles using mapnik as our tile server.<br><br>thanks.<br>Enzo<br>
