We study a crossing minimization problem of drawing a bipartite graph with a radial layout of two orbits. Radial layouts have strong application in social network visualization, displaying centrality of actors. The problem is called the one-sided crossing minimization if the positions of vertices in one of the two orbits are fixed, and is known to be NP-hard. We present the first approximation algorithm, proving that the one-sided crossing minimization in a radial layout is 15-approximable.
