Wow, that's awesome! We definitely need to get this into sage. Even for plotting graphs it would be very nice, since it would help greatly being able to move around vertices in order to disambiguate the plots. For example, yesterday when teaching graph theory in my Sage class (http://wiki.wstein.org/09/480b) we plotted some complement of the Kite graph, and it very much looked like there were edges between certain vertices, but there weren't. It's just that the graph layout algorithm had placed vertices exactly on top of edges between other vertices. If one could move the vertices a little, it would be easy to disambiguate. And note that 3d plotting didn't help in this case, because for no good reason there are no vertex labels on 3d graph plots. We ended up using layout="circular", which helped enough. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
