SVG (Scalable Vector Graphics) is a W3C recommendation. It is a royalty-free vendor-neutral open standard developed under the W3C Process and it has a strong industry support.
This standard defines an XML (Extensible Markup Language) grammar for 2D graphics which includes features such as transparency, arbitrary geometry, filter effects (shadows, lighting effects, etc.), scripting and animation.
SVG drawings can be interactive and dynamic. Animations can be defined and
triggered either declaratively (i.e. by embedding SVG animation elements in SVG
content) or via scripting.
SVG files can also be visualized by external applications such as ADOBE
products, JASC or BATIK.
