Due to data compression or low resolution, nearby vertices and edges of a graph drawn in the plane may be bundled to a common node or arc. We model such a “compromised” drawing by a piecewise linear map. We wish to perturbby an arbitrarily smallinto a proper drawing (in which the vertices are distinct points, any two edges intersect in finitely many points, and no three edges have a common interior point) that minimizes the number of crossings. An-perturbation, for every, is given by a piecewise linear mapwith, whereis the uniform norm (i.e.,norm). We present a polynomial-time solution for this optimization problem whenGis a cycle and the maphas nospurs(i.e., no two adjacent edges are mapped to overlapping arcs). We also show that the problem becomes NP-complete (i) whenGis an arbitrary graph andhas no spurs, and (ii) whenmay have spurs andGis a cycle or a union of disjoint paths.
