The choice of diagramming solution was not easy, we evaluated 15 products and all had Pro's / Con's. When we finally got it down to two options (yFiles and JointJS+) we felt that the mix: using SVG, being open source with great sample code, a solid community with partners we could augment our team with and professional support from the JointJS team meant we were only left with one obvious choice. So we chose JointJS+ and opted to work with their custom development partner who we were introduced to and were able to get a solution to our immediate need live in 5 weeks, while leaving ourselves with a long term strategic solution.
