The gnomonic projection is available as d3.geo.gnomonic. See also the interactive version.
This is copied from mbostock's example
It shows what happens when you start a transition and select shit that would also include shit but it's not inside the async function where it's getting created so it never gets selected and transitioned.
Based on Mike Bostock’s [World Map][0], modified to automatically colour countries such that no adjacent countries share the same colour.
This is done by extracting the topology via [TopoJSON][1] and greedily picking colours until the constraint is fulfilled.
See also: [Graph coloring][2] on Wikipedia.
Update: Greedily colouring is now performed in a single line, thanks to Mike Bostock!
#Generate cities data
wget http://download.geonames.org/export/dump/cities15000.zipunzip cities15000.zipnode geonames.js cities15000.txtThe result is json array of cities in the following format:

Like my other recreation of the xkcd:1335 map projection, but rotated to solar noon at 12 o’clock and with the solar terminator overlaid. The blue region is night. The map updates continuously.
