The empty space around
*n*disjoint line segments in the plane can be partitioned into*n*+ 1 convex faces by extending the segments in some order. The*dual graph*of such a partition is the plane graph whose vertices correspond to the*n*+ 1 convex faces, and every segment endpoint corresponds to an edge between the two incident faces on opposite sides of the segment. We construct, for every set of*n*disjoint line segments in the plane, a convex partition whose dual graph is 2-edge connected. **Updates**:- Unfortunately this paper is flawed.
