Draw graphics using JavaScript:
<canvas id="myCanvas" width="400" height="200"></canvas> <script> var canvas = document.getElementById("myCanvas"); var ctx = canvas.getContext("2d"); ctx.fillStyle = "red"; ctx.fillRect(20, 20, 150, 100); </script>
SVG enables defining vector graphics:
<svg width="100" height="100"> <circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red" /> </svg>
