JointJS+ was really a great find, as it gave us a great boost in the diagramming frontend of our application. These guys know their business and give you a great support on your development. One of our requirements was to have a BPMN diagram support in our app and they quickly supplied this as a plugin to JointJS+!

JointJS allowed us to quickly develop a tool to generate single-line schematics for our network and easily integrate it into our permit management tool. We also plan to integrate it into another tool in the near future because it offers more functionality and flexibility.
