npm install dom-to-points
If you want to get an SVG like the red thing below
``
yarn add dom-to-points // Package size: 795 B
`javascript
import {getPolygonString} from 'dom-to-points'
// or const {getPointsArray, getPolygonString} = require('dom-to-points')
const points = getPolygonString('.item')
// or const points = getPolygonString([...document.querySelectorAll('.item')])
console.log('polygonString', points)
/*

`javascript
const points = getPointsArray('.item')
// or const points = getPointsArray([...document.querySelectorAll('.item')])

You could make a polygon with the data and add it to an SVG.
You could use a library, such as SVG.js or paper.js
