Visualisation of Large and Complex Scale-free Networks (Ahmed, Dwyer, Hong, Murray, Song, Wu)
Scale-free networks appear in many application domains such as social networks and biological networks. We designed new visualisation methods of scale-free networks in 3D. To make effective use of the third dimension with minimum occlusion, we use the concept of layered drawings and concentric spheres, constraining nodes to lie on parallel planes or the surface of spheres, based on the degree of nodes.
Experimental results with real world data sets show that our method can be useful for visual analysis of large and complex scale-free networks.
