Strictly-Convex Drawings of 3-Connected Planar Graphst-known area bound for such drawings is ., as shown by Bárány and Rote by means of a sophisticated technique based on perturbing (non-strictly) convex drawings. Unfortunately, the hidden constants in such area bound are in the . order..We present a new and easy-to-implement technique that yields str

Rectilinear Planarity of Partial 2-Trees a long-standing open problem to establish a tight upper bound on its complexity for partial 2-trees, i.e., graphs whose biconnected components are series-parallel. We describe a new .-time algorithm to test rectilinear planarity of partial 2-trees, which improves over the current best bound of .. M

Computing a Feedback Arc Set Using PageRank than the ones produced by the best previously known heuristics, often reducing the FAS size by more than 50%. It is based on computing the PageRank score of the nodes of the directed line graph of the input directed graph. Although the time required by our heuristic is heavily influenced by the siz

Migrant Hospitalities in the Mediterraneanan open question whether every simple drawing of a complete bipartite graph . contains a plane spanning tree as a subdrawing. We answer this question to the positive by showing that for every simple drawing of . and for every vertex . in that drawing, the drawing contains a ., that is, a plane spann

However, they can create overlaps between nodes which hinder the exploration process by hiding parts of the information. It is therefore of utmost importance to remove these overlaps to improve graph visualization readabilit
