Hi Julie, I still don't understand if you generate the circles in the client, using Javascript or on the server.
In the first case, that might be one of the reasons why it is very slow. If you generate the circles on the server, than you can as well aggregate the circles. I had a similar problem where I had to display thens of thousands of positions in a map. I ended up aggregating the elements using SQL functions in the database. Every time the user zooms and pans he would just download and see the portion of the map he navigated to. The more the user zoomed in the less the positions where aggregated. It really worked well and with no loss of quality. It makes no sense to display thousands of elements if they all overlap and just create one big soup of circles ... Otherwise you might also want to look at other technologies besides SVG. SVG does not fit everywhere. Or wait for a better SVG viewer ... or create a raster version of your SVG and send the raster to the client.
