A Space-Based Layout Algorithm for the Drawing of Co-citation Networks

We present in this paper a drawing algorithm to represent graphically co-citation networks (scientograms). These networks have some interesting and unusual topological properties which are often valuable to be visualized. In general, these networks are pruned with a network scaling algorithm, then visualized using a drawing algorithm [3]. However, typical drawing algorithms do not work properly, especially when the size of the networks grows. Edge crossings appear while the drawing space is not adequately filled resulting in an unsightly display. The approach presented in this paper is able to print the networks filling all the available space in an aesthetic way, while avoiding edge crossings. The algorithm is detailed and compared with the classical Kamada-Kawai drawing algorithm on two maps.
