There seems to be a bug in voronoi clipping; setting .clipExtent([[-1, -10], [width + 1, height + 1]]) works around the issue for these particular points.

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!

Australia↔Austria
Trying to figure out if there’s a problem with Australia↔Austria spherical linear interpolation in the [World Countries][1] example, as hinted at by Hadley Wickham.
Note how the geodesic is always a straight line under the orthographic projection, since it is always going through the centre. (Except for the initial view centred at (0°, 0°), which is not on the geodesic). This is true for all azimuthal projections.

World Boundaries TopoJSON
A demo of Mike Bostock’s TopoJSON using states & provinces boundaries from Natural Earth.
With simplification turned on (-s 100), this reduces the original 57MB GeoJSON file to a mere 515KB!
