There is an alternative solution to patricksurry's answer, by using quaternion representations, as inspired by Jason Davies. I, too, thought D3 would've already supported this composition natively! And hoped Jason Davies posted his code...
Took sometime to figure out the math. A demo is uploaded here, with an attempt to explain the math too. http://bl.ocks.org/ivyywang/7c94cb5a3accd9913263
With my limited math knowledge, I think, one of the advantages quaternion over Euler is the ability to compound multiple rotations over and over, without worrying about coordinate references. So it would always work, no matter where your north pole faces, and no matter how many rotations you'll have. (Someone please correct me, if I got this wrong).
