Drawing Graphs on Two and Three Lines

Abstract We give a linear-time algorithm to decide whether a graph has a planar LL-drawing, i.e., a planar drawing on two parallel lines. We utilize this result to obtain planar drawings on three lines for a generalization of bipartite graphs, also in linear time.
