  1. Interactive Visualization of Small World Graphs An implementation in prefuse

  2. The Problem • How do we display Small World Graphs?

  3. Why is this hard? • Clusters! • Hierarchies!

  4. The proposed solution • Physics • Dendrogram Clustering • Degree of Abstraction (DOA) • Details in paper

  5. The Gist

  6. Prefuse

  7. SMALL WORLD GRAPH

  8. SMALL WORLD GRAPH Physics and Clustering

  9. SMALL WORLD GRAPH Handle Occlusion in 2D DOA Layout Physics and Clustering

  10. What’s Done? SMALL WORLD GRAPH Handle Occlusion in 2D DOA Layout Physics and Clustering

  11. 80% Done Occlusion in 2D SMALL WORLD GRAPH Tubes as rectangles with gradient Draw nodes as X layers one layer at a time Explicitly compute Voronoi regions Handle Occlusion in 2D DOA Layout Physics and Clustering

  12. 50% Done DOA Layout SMALL WORLD GRAPH • Things become more/less abstract in relation to the cursor • 3 different focal areas • BUT • Some strange discontinuities (bugs) • Need to integrate geometric distortion Handle Occlusion in 2D DOA Layout Physics and Clustering
