In addition, it should be noted that browser support for SVG has proven to be incomplete - currently a large number of browsers, including Internet Explorer, require an additional plugin (which many users will not have) to display the SVG image. Specifically, SVG Tiny (SVGT) and SVG Basic (SVGB) are subsets of the full SVG standard primarily intended for use on a device with disabilities such as mobile phones or PDAs. There are several versions of the SVG format in use today (SVG 1.0, SVG 1.1, and SVG Tiny 1.2 at the time of this writing). SVGZ format is a modified SVG format that uses GZIP compression and thus solves the problem of large SVG file sizes.

Support for vector shapes (such as lines, curves, etc.).The SVG format is used for both static and animated graphics. SVG is based on the XML markup language, and was developed as an open standard by the World Wide Wide Consortium. The SVG extension (Scalable Vector Graphics) is used primarily for vector graphics and is an open format.
