A Scalable Vector Graphics is a technology used for creating vector graphics in a browser.
The SVG technology is based on the XML file format and it is a language for describing 2D-graphics and graphical applications in XML files which than are being rendered by an SVG viewer.
SVG is mostly useful for vector type diagrams like Pie charts, two-dimensional graphs in an X,Y coordinate system and similar presentational tools. This "technology" is an open standard that has been actively developed by the W3C since 1999.
NOTE: Although HTML5 does support embedding SVG based objects, the SVG is actually not a part of the HTML5.
The SVG element accepts width and height attributes that define the width and height of the SVG object to be embedded.
