Our 2003 presentations for IALLT and WorldCALL had some cool SVG stuff in them, which at the time was only working in special builds of Mozilla. Now, many browsers (Firefox, Safari, Webkit, Midori, and Opera) have support for SVG, but some of the code has broken in the interim as user agent implementations shook down, so I fixed bugs, added one new feature (redraw the tree optimally in the browser window when it's resized), and updated links, references and explanations. These materials are now working, and even more interesting because the SVG functionality is now broadly available.
