The workshop is organised by the Creative Industry Knowledge Transfer Network and was held at the Nesta in London. The workshop had some excellent speakers and I am quite honoured to be invited. Below are the presentation slides.
This is presented at the Visual Analytics Summer School 2013, and below are the slides
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.
The conference will be in Sydney, Australia next year and I really hope I can attend.
This is an entry to the Mini Challenge 1 of the VAST Challenge 2012. The details are here. Below is a video describing the solution.

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.
