canvas element canvas is an HTML element for
drawing graphics by scripting (usually with JavaScript).
<canvas>
was first introduced by Apple and is now specified by
WHATWG. It is
supported by Safari 1.3+, Firefox 1.5+ and Opera 9+. Support in
Internet Explorer is faked (imperfectly) by using Google's ExplorerCanvas.
Graphics in <canvas>
are resolution-dependent and, at least for now, 2-D only.
