After the canvas is shown can I draw stuff (lines, points) on it?

It sgould be posssible, yes. The canvas object is available, so you can use it as usual

but when i try i get errors, namely: // after the kernel declarations, etc., I do const canvas = render.canvas; // should I do this? //canvas.setAttribute('id', 'canvas'); document.getElementsByTagName('body')[0].appendChild(canvas); // the code below won't work /* function draw() { var canvas = document.getElementById('canvas'); if (canvas.getContext) { var ctx = canvas.getContext('2d'); ctx.beginPath(); ctx.moveTo(75, 50); ctx.lineTo(100, 75); ctx.lineTo(100, 25); ctx.fill(); } } draw();/
