This is the radial variant of our Parallel Edge Splatting technique. The original vertical stripes are now mapped to circle annuli and the graph edges as curved links in between the two corresponding circle circumferences.
This approach has two benefits. Formerly long links are reduced in their lengths and the approach allows robust visual patterns under a vertex shifting operation.
On the negative side, the circular stripes become even narrower than in the Cartesian variant but from our opinion the resulting diagrams look more aesthetically pleasing. Interactive features are definitely needed to support better explorations of the dynamic graph data.
