A sample map, adapted from mbostock's UK example, centered on NYC.

For this commit, the geo file was simplified using topojson because the number of points javascript and SVG were processing was lagging out, hard.
I ran the same topojson command as last commit, but with --simplify-proportion .03
Use topojson quantization (-q 1e5), too
Revert "Use topojson quantization (-q 1e5), too" :: the default topojson quant is actually 1e4, but 1e3 is too small, so leave it at the default.

This reverts commit 7bd9eb1c3788484e86d6f6b576ff43376220658f.
This edit to server is necessary to allow topojson and whatnot to go through.
