I have removed Antarctica from my TopoJSON file and now there's a big margin at the bottom of the d3 map:

As a result, when zooming in and panning there's a huge blank space at the bottom. I've been trying for the past hour to fix this, but wasn't able to. I can't figure out if what needs changing is the TopoJSON file or if I can make this using the d3 projection and zoom behavior code.
HELP!
