We are producing graphs all the time (representing all sorts of combinatorial/algebraic data), and have been dreaming of such a life saving feature for years. We would just further need support for: - Displaying vertex labels. In a perfect world, that would include latex labels. But string labels (especially with support for newlines) would already do the job in most cases. - Customizing the size of the edition window (typically to make it as wide as the browser's frame).

[sage-devel] graph editor -- devel doc
Hi, The new graph editor in sage by Rado is AWESOME. One can try it easily at http://sagenb.org by typing: g = graphs.CompleteGraph(10) graph_editor(g) The actual source code is at local/lib/python/site-packages/sagenb-0.6-py2.6.egg/sagenb/data/graph_editor/ It would be *GREAT* if there were a README.txt file in that directory that explained what all the js files actually are, something about how the graph editor works, where the code that does spring layout dynamically is located, etc. I looked at the code for five minutes and couldn't deduce answers to any of those questions. So, could somebody familiar with the graph editor write something and post a patch. Or just respond to this email with what would go in a README.txt? I have two undergrads who might want to work on that code, but it would help a lot of there were some docs.

Re: [sage-devel] graph editor -- devel doc
I agree that it's awesome. I'm not sure if I'm using it right though. If I remove a vertex from Williams example below, and then click Save, it changes the cell, but the graph that it then creates is the same as before I removed the vertex. The same problem seems to occur for most changes I make to the graph (though I somehow got it to add a vertex and pair of edges at one point; I'm no longer sure how). Can other people duplicate this? This looks like a bug, but I'm not quite sure what the designed behavior is. ;-) David On Thu, Jan 21, 2010 at 3:22 PM, William Stein wst...@gmail.com wrote: Hi, The new graph editor in sage by Rado is AWESOME.
