sci@gentoo.org Gentoo Science Project JGraph X is based on the mxGraph architecture, a re-designed core based on JGraph experience. Overall, JGraph X provides more features that JGraph, with a far smaller code size and complexity. Redesigning the codebase from scratch now means implementing common feature extensions are easier and require less coding. A number of new loosely coupled application-centric features have been added, making prototyping even faster, without their usage restricting application flexibility.
