If you write the Javascript side, then I can do the interact side. > > It would be nice if there was something like "developer's guide to > interacts", explaining the logic behind interacts and the minimum code > to get a new interact (with any random JS) into Sage.

I think you basically have to follow what is done by any other interact control in the file interact.py, which is part of the Sage notebook code. > > Rado > > On Mar 28, 6:02 pm, Rob Beezer <goo...@beezer.cotse.net> wrote: >> Kevin Clark and Rado Kirov have been advancing the graph editor lately >> [1], [2].
