This is an simple example

javascript``` const canvas = new altizurePluginInteractivePolygon.Canvas({ canvas: document.getElementById('canvas'), sandbox })

const polygon = canvas.addPolygon()

let points = []

polygon.once('close', () => { points = polygon.vertices.map(vertex => vertex.position) // [{ x, y }] })

polygon.draw() // start drawing with user interaction

canvas.clear() // remove all its child

canvas.destruct() // remove all its child and listeners
