function drawPoint(ctx, y, x, r) {

ctx.beginPath();

ctx.arc(x, y, r, 0, 2 * Math.PI);

ctx.fillStyle = COLOR;

ctx.fill();

}

You might realize that some context methods are those we saw in Chapter 5. The only exception is ctx.arc(), one that draws circles.

After drawPoint(), create drawSegment(), a function that draws the lines between keypoints:function drawSegment([ay, ax], [by, bx], scale, ctx) {

ctx.beginPath();

ctx.moveTo(ax * scale, ay * scale);

ctx.lineTo(bx * scale, by * scale);

ctx.lineWidth = '10px';

ctx.strokeStyle = COLOR;

ctx.stroke();

}
