Spirality of orthogonal representations and optimal drawings of series-parallel graphs and 3-planarnar embedding of a planar graph such that its orthogonal drawing has the minimum number of bends is a fundamental open problem in graph drawing. This paper provides the first partial solution to the problem. It gives a new combinatorial characterization of orthogonal drawings based on the concept of

Recent work [4] has shown that parallel algorithms that are sensitive to the size of the input domain can improve on more general parallel algorithms. The cited paper demonstrates an .(log log log .)-ste
