When the hybrid projection is purely orthographic, clipping angle is great: the clip angle is the same in all directions. Here it should be 90 degrees. When the equirectangular is dominant in the hybrid projection, the clipping angle is not needed (I use an angle of 180 degrees, which doesn't clip anything below).

WebWeâ ve got our geodata. Now get ready to rock. First, we define our first path generator:. var path = d3.geo.path();. d3.geo.path() is a total lifesaver of a function.
