the map such that distortion is acceptable.
Cable plans are used for documenting the layout of communication networks. They
are drawn orthogonally and try to preserve the angles, but not the distances of
the original embedding.
Compared to the orthogonal drawing of (embedded) graphs [Tam87], the introduction of
