Example on canvas
it draws a rectangle on a canvas context black color by default

<html>
<canvas id="canvas"></canvas>
<script type="text/javascript">
        var context = canvas.getContext("2d")
// stroke a 100px square at 0, 0
context.rect(0, 0, 100, 100)
context.stroke()
</script>
</html>

Save and open it in your browser you should see a square on the top right corner of your browse window
