Visualization of graphs containing many nodes and edges efficiently is quite challenging since representations generally suffer from visual clutter induced by the large amount of edge crossings and node-edge overlaps. That problem becomes even more important when nodes po- sitions are fixed, such as in geography were nodes posi- tions are set according to geographical coordinates. Edge bundling techniques can help to solve this issue by visu- ally merging edges along common routes but it can also help to reveal high-level edge patterns in the network and therefore to understand its overall organization. In this pa- per, we present a generalization of [18] to reduce the clut- ter in a 3D representation by routing edges into bundles as well as a GPU-based rendering method to emphasize bundles densities while preserving edge color. To visualize geographical networks in the context of the globe, we also provide a new technique allowing to bundle edges around and not across it.
