Following a request from a user, js-graph.it has been redistributed in version 1.1 under the ASL 2.0 license.
This is less restrictive than LGPL, so this change hopefully shouldn't cause any problems to anyone.
Version 1.0 is available with plenty of bug fixes and some new features
A heavy refactoring is in progress in order to simplify extendability and add new features such as connectors routing strategies different from the "S" connector. A fully compatible new version will be soon available.
