In terms of rotating the source data for a normal 2D map, you just have to
re-calculate the positions on the nodes based on a rotation angle and
center of rotation. The ways/relations would automatically follow suite.

I suspect that this would be relatively easy to code in
perl/python/awk/etc., anything that is trig aware.

As long as the distances weren't too great you wouldn't see any/much
distortion.
