Hello again, As promised here is an updated version.
http://www.math.uiuc.edu/~rkirov2/processing/grapheditor.html Controls are cleaned up (almost all mouse now). If you see something buggy email me (or even better fix it :) the code is in page). I think I will add some simple control for cloning vertices (i.e. inheriting all the edges) in the future. The controls are heavily inspired by Rob's java applet. It was the one I liked the most because of its simplicity. I am a proponent of simple vs. complex since running processing over javascript is a hack to start with. I doubt we can push it too much, without breaking something. One major problem I see so far is that CANVAS js element has problems with putting text. Processing JS has a workaround that works only on firefox, which I don't think is good enough. So until something changes, the graphs will have no labels :( Maybe jquery can overlay html elements ... For the next update I will try to include a simple "live" graph implementation (i.e. real-time spring embedding) and graph input (i.e. copy/paste from SAGE -> JS editor). Fidel, thanks for the contribution. I have put it on the page. Email me if you want your name to link to a homepage. In the version that would go with SAGE we should hide that output and put everything in the g.latex() function (which i see you are working on). RJF, thanks for the paper. I skimmed over it, but bezier curves might be an overkill for now. Say I manage to put them in JS (processing has build in bezier curves) is there a good way to pass those to NetworkX (which from what i understand is how g.show works). In any case the way I see it is g.show to be the last stop before the pretty picture pops out not the js editor. The editor should be intermediate step for little tweaks.
