• Centrality Based Visualization of Small World Graphs 

  Ham, Frank van; Wattenberg, Martin (The Eurographics Association and Blackwell Publishing Ltd., 2008)

  Current graph drawing algorithms enable the creation of two dimensional node-link diagrams of huge graphs. However, for graphs with low diameter (of which "small world" graphs are a subset) these techniques begin to break ...

• Visual Inspection of Multivariate Graphs 

  Pretorius, A. Johannes; Wijk, Jarke J. van (The Eurographics Association and Blackwell Publishing Ltd., 2008)

  Most graph visualization techniques focus on the structure of graphs and do not offer support for dealing with node attributes and edge labels. To enable users to detect relations and patterns in terms of data associated ...
