This demonstrates using topojson.merge, a new feature in TopoJSON 1.6, to merge multiple polygons into a single polygon whilst removing interior borders. (An alternative approach is to draw the polygons twice.)

Unlike mbostock's original example, this uses a pre-projected topojson file and a null projection.

Side by side leaflet (Toner comparison)

Comparison of Stamen Design's previous Toner style with new Toner data as of 2014.

Borrowed from Andrew Harvey's gist here and his live demo.

Zoomable raster world map (which happens to be using Stamen's Map Stack).

Apparently I broke it by trying a projection other than the original. :(

Based off Calvin Metcalf's version, which in turn is based off Jason Davies map which is a combination of Mike Bostock’s raster reprojection, automatic projection tiles and a MapBox terrain example.

Thanks to Mike Bostock and Nelson Minar for their comments and encouragement! And Obviously Jason Davies for making the original.
