Projection

At the moment the only projection used on this script, when you add the parameter -p, is an equirectangular and a size 960x500:

width = 960, height = 500, d3.geo.equirectangular().rotate([-11.0, 0.0, 0.0]).scale(width /(2 * Math.PI)).translate([width / 2, height / 2])

You can edit it on the script if you targeting another projection. Here's [an example](Here's an example of where it's used) of where it has been used
