  <polyline
    id="example"
    stroke="black"
    fill="none"
    points="50,0 21,90 98,35 2,35 79,90" />
</svg>

const example = document.getElementById("example");
const point = document.getElementById("svg").createSVGPoint();
point.y = 10;
point.x = 10;
console.log(example.points.appendItem(point));
