As a practise for HTML, I also composed this heart to practice both shapes such as curves and lines, as well as finer details such as colors and stroke details.
The code for this image is as follows:
<!DOCTYPE HTML>
<html>
<head>
<script>
window.onload = function() {
var canvas = document.getElementById("myCanvas");
var context = canvas.getContext("2d");
////////////////////////////////////// start below this line ˇˇˇˇˇˇˇˇˇˇ
var x = 400;
var y = 200;
var controlx1 = 300;
var controly1 = -10;
var controlx2 = 50;
var controly2 = 150;
var endx = 200;
var endy = 320;
var controlx3 = 320;
var controly3 = 400;
var endx2 = 400;
var endy2 = 550;
var controlx4 = 480;
var controly4 = 400;
var endx3 = 600;
var endy3 = 320;
var controlx5 = 750;
var controly5 = 150;
var controlx6 = 500;
var controly6 = -10;
context.beginPath();
context.moveTo(x, y);
context.bezierCurveTo(controlx1, controly1, controlx2, controly2, endx, endy);
context.quadraticCurveTo(controlx3, controly3, endx2, endy2);
context.quadraticCurveTo(controlx4, controly4, endx3, endy3);
context.bezierCurveTo(controlx5, controly5, controlx6, controly6, x, y);
context.closePath();
context.lineWidth = 20;
context.fillStyle = 'rgb(255, 0, 0)';
context.fill();
context.strokeStyle = 'rgb(150, 0, 0)';
context.stroke();
////////////////////////////////////// end above this line ˆˆˆˆˆˆˆˆˆˆˆˆˆˆˆ
};
</script>
</head>
<body>
<canvas id="myCanvas" width="800" height="600"></canvas>
</body>
</html>
