What is SVG?
SVG (Scalable Vector Graphics) is an open standard language for
describing two-dimensional (2D) graphics in XML. It is a W3C
recommendation. SVG allows for three types of graphic objects: vector
graphic shapes (e.g., paths consisting of straight lines and curves),
images and text. Graphical objects can be styled, transformed and
composited into previously rendered objects. The feature set includes
nested transformations, clipping paths, alpha masks, filter effects and
template objects.
Where do I find the SVG specification?
The SVG specification is available at http://www.w3.org/TR/SVG/.
