Dagstuhl Seminar: Information Visualization – Towards Multivariate Network Visualization

This is the second Dagstuhl Seminar I attended this year. Just as before, it is very interesting and intensive. Met several old friends and got to make a lot new friend. I am busy writing a book chapter on Multivariate Network Visualization now as the result.

Dagstuhl Seminar: Drawing Graphs and Maps with Curves

Dagstuhl Seminar is an invitation only workshop that experts from all over the world to work on  a specific topic intensively for a week in a remote research institute (an old castle) in Germany. This one is about curved edges in graph visualisation, which I just did a study last year.

A User Study on Curved Edges in Graph Visualisation

Kai Xu, Chris Rooney, Peter Passmore, and Dong-Han Ham, “A User Study on Curved Edges in Graph Visualisation”, Seventh International Conference on the Theory and Application of Diagrams, 2-6 July 2012, Canterbury, UK. PDF

Recently there has been increasing research interest in visualizing graphs with curved edges to produce more readable visualizations. While there are many automatic techniques, little has been done to evaluate them empirically. In this paper we present our study on the impact of edge curvature on graph readability by comparing the path finding performance on graph visualizations with varied curvature levels. We also asked the participants to provide subject ratings of the effectiveness and aesthetics of different types of curved edge.
