How to implement such animation on SVG?

Question

SVG

1. How can I implement such a block so that I can change the picture

And 3. If it is possible to create random lines of this kind,

please tell me how to implement this, at least a link to the source where they do this. The problem is that there is no idea how to envelop this kind of figure with a line.
