Does anyone know if they are using any UI toolkit for the nodes/edges blocks or have they built it themselves? I am looking for something something similar but for different purpose, just the ui toolkit without any logic built on top of it
JointJS is quite great for that: https://www.jointjs.com, even with the community version https://www.jointjs.com/comparison => we have built some node ui with it and it has been fast, flexible and extensible; maybe not easy to start with, but it was worth it
