Draw bezier curve smoothly between two points. Just like the curves in mind maps.

	var c = document.getElementById("myCanvas");
	var ctx = c.getContext("2d");
	drawCurve(ctx, 100, 80, 0, 100);

	function drawCurve(ctx, x1, y1, x2, y2){
	ctx.beginPath();
	ctx.moveTo(x1, y1);
	ctx.bezierCurveTo((x1+x2)/2, y1, (x1+x2)/2, y2, x2, y2);
	ctx.stroke();
	}
