Zoomable raster world map on an Lambert Conic Conformal aka Massachusetts State Plane.

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.

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!
