Firefox, Safari and Opera 9 support the canvas tag to allow 2D command-based drawing. ExplorerCanvas brings the same functionality to Internet Explorer. To use, web developers only need to include a single script tag in their existing web pages.

<canvas> is a new HTML element which can be used to draw graphics via scripting (usually Javascript). For example, it can be used to draw graphs, make photo compositions or even perform animations.

Mozilla applications gained support for <canvas> starting with Gecko 1.8 (i.e. Ff1.5). The element was originally introduced by Apple for the OS X Dashboard and Safari. Internet Explorer does not natively support <canvas>, but a page can effectively add support for it by including a script from Google's Explorer Canvas project. Opera 9 also supports <canvas>.
