Drawing Metro Maps using BCurves

The automatic layout of metro maps has been investigated quite in- tensely over the last few years. Previous work has focused on the octilinear drawing style where edges are drawn horizontally, vertically, or diagonally at 45 . Inspired by manually created curvy metro maps, we advocate the use of the curvilinear drawing style; we draw edges as Bcurves. Since we forbid metro lines to bend (even in stations), the user of such a map can trace the metro lines easily. In order to create such drawings, we use the force-directed framework. Our method is the first that directly represents and operates on edges as curves.
