Customizable JS Wrapper for Diagram Component

There is a component https://gojs.net/latest/samples/dynamicPorts.html made in js. You need to write a wrapper in JS to work with this graph. It is necessary to create high-level functions for adding and deleting diagram elements, as well as adding and deleting connections (if they are in the original component, this means moving it up a level for single access from the wrapper. Also convert saving-loading to OOP format (with duplication of the domain model in JS types).

I have the terms of reference, I will send it to the candidate for review.
