How to implement sticky drag in Snap.SVG?

Question

JavaScript

Using the Snap.SVG library in the picture, I outline the details using the polygon element, since they are located close to each other, often polygons overlap each other, or are obtained at an unaesthetic distance. You can align exactly by zooming in to 500%.
Is it possible to make the points stick together when they are close?
