After spending time evaluating other libraries I was pleased to find one that would satisfy all of my requirements with no restrictions on customisationThis is a truly powerful and flexible library. Just about any feature can be fully customised and made modular with good decoupled architecture.

Good documentation and an extensive, and increasing, list of demos that can be used as a boilerplate to accelerate your product,Every concept can be fully customised - custom shapes, ports, inline editors, links … the list goes on.As its build on SVG it is very fast and works well with CSS and other HTML elements

I think I've only touched the surface. The learning curve is quite steep but the tutorials and demos do help understand how things can be done.

I was the engineer that implemented the component and it provided everything I needed. As with any component, there was a learning curve but overall I was never stuck on anything for too long and I feel like we provided a great experience to our users.

JointJS+ is easy to use, has clear documentation and the folks at Client.IO provide great support. The feature set is rich enough to give you everything you need to build a first in class designer experience.

Not sure I have much here. As an engineer using third party components, you expect a certain number of hiccups or bugs in the component. I feel like the JointJS+ tool has very few of these hiccups and even when they show up, they are fairly easy to work around. No real cons for me.

The data visualization helps understand the application very quickly

Ease of user and easy to implement, a quick and easy way to implement modeling and design the schema.

I explored JavaScript language only due to project which is quite interesting. will explore the angular and typescript language as well if free trial get extended.

All the contents are fabulous and process + Industries must use this library to smoothen their manufacturing activities.

Extensive documentation to get started quickly, and the demos are very useful as well. Have just started trialing to compare with other diagramming tools, and the communication so far is awesome.The UI library is more useful than I initially thought as well, the team has thought of all common use cases. Despite being over 10 years since conception, seems like the team has continuously kept the code and features updated which is a big plus.JointJs renders in pure SVG instead of canvas, making it much easier to dev and debug as well.

Not a blocker, but would be nice if backbone.js was not a dependency. The integration with modern frameworks (e.g. React/Vue) is not ideal because of this, with no easy way to get 2-way data binding to work with components/state management libraries.
