Quality Ratios of Measures for Graph Drawing Styles

When comparing two dierent styles to draw a graph, one can wonder how much better or worse one style can be than another one, in the worst case, for some quality measure. We compare planar straight-line drawings with xed and free embeddings, planar circular arc drawings, and non-planar straight-line drawings, and consider the quality measures angular resolution, area requirement, edge length ratio, and feature resolution.
