2. Drawing lines in Mozilla based browsers and the Internet Explorer

HTML itself is not able to describe lines. Therefore, there is no built-in feature in the above-mentioned browsers for drawing lines. By implementing the Bresenham algorithm with JavaScript while applying some tricks, we will be able to draw lines in a good manner in respect to the browser runtime and memory footprints.

5. Raphael: JavaScript Drawing Library

Raphael uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.
