10. Worke don this project where Clients were doctors who wants to build up a system where everyone can practice world class high value effective care. It was an idea to build a free coordinate system for the doctors where they can design prescriptions for their patients accordingly. So to create a free coordinate along with multiple types of different nodes that can connect with each other, we’ve been using ruby on rails at back-end and used a JavaScript library js-plumb. We can perform multiple actions on nodes e.g (store a video, content, Doctors prescription or attachment of a node with another node and a lot more).
