The map was generated using continent-level shapefiles (I believe from here: http://pubs.usgs.gov/of/2006/1187/basemaps/continents/). We stuck with continent-level outlines because adding country boundaries would have needlessly complicated the SVG, and borders can sometimes be disputed and controversial things :)

It would have been nice to have the great lakes and caspian sea, because they're such large features but with a team of two webdevs, some things have to wait until version 2.

Also, there's a ton of downloads coming from a point in Northeast Siberia where, as far as I can tell on Google Maps, there isn't so much as a log cabin. Mapping anomaly, or giant, secret military base?

The svg was generated from the shapefiles here: https://github.com/potch/glow/tree/master/shapefile. I need to ask potch where the shapefiles come from.

Inner regions like lakes weren't included since they would complicate the svg without a lot of benefit.

Also missing the Great Lakes in North America.
