Canvas

The canvas tag was introduced by Apple and has been standardized to become part of HTML5.

To use it, you add the canvas tag to your HTML page, then use javascript draw on it.

<canvas id="canvas" showsrc> function draw() {

 c = document.getElementById("canvas");
 p = c.getContext("2d");
 p.fillRect(50, 50, 150, 150);

} </canvas>
