Special Issue on Selected Papers from the Sixteenth International Symposium on Graph Drawing, GD 2008
Visual Analysis of One-To-Many Matched Graphs
Vol. 14, no. 1, pp. 97-119, 2010. Regular paper.
Abstract Motivated by applications of social network analysis and of Web search clustering engines, we describe an algorithm and a system for the display and the visual analysis of two graphs G1 and G2 such that each Gi is defined on a different data set with its own primary relationships and there are secondary relationships between the vertices of G1 and those of G2. Our main goal is to compute a drawing of G1 and G2 that makes clearly visible the relations between the two graphs by avoiding their crossings, and that also takes into account some other important aesthetic requirements like number of bends, area, and aspect ratio. Application examples and experiments on the system performances are also presented.
