1⟩ What is SVG and what is VML ?
SVG (Scalable Vector Graphics) is a format which is recomended by the W3C for the description of vector graphics, especially for the use in Web pages. In order to view a page with included SVG objects, you must install a plugin for your webbrowser. You can get one for free from http://www.adobe.com/svg/. There are plugins available for many webbrowsers.
