<svg id="svg" viewBox="-10 -10 120 120" xmlns="http://www.w3.org/2000/svg">
<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;
