I had some fun creating a pure HTML-DOM based Force-directed graph layout, similar to a touchgraph (http://www.touchgraph.com/) view.
Built with the help of jQuery (hereby again: wonderful library), no canvas or SVG used (only DOM manipulations). You can see an experimental demo at: http://jowl.ontologyonline.org/TouchGraph.html. and the blog post: http://ontologyonline.blogspot.com/2009/01/experimental-touchgraph-visualization.html. Room for lot's of improvement, but nevertheless quite happy with the result already. David Decraene http://ontologyonline.org
