What to use to create links for html blocks?

Question

JavaScript

Good afternoon! I had a problem how to make such a construction of links for html elements.

Demo

There is a test link
I thought so, take a snap svg or Raphael and try to implement what was planned. Or make the whole circuit directly on canvas, which is probably more difficult and labor-intensive.
They also suggested using d3.js . I also found such a thing
. Tell me how to be? There are those who have implemented something similar or maybe you have examples of such implementations?

Answer 1

Interesting service. Intrigued. I'm interested in the question about svg

Answer 2

Draw on canvas. It can be entirely, but only lines can be. I will suggest the latter.
