What Is SVG? The Scalable Vector Graphics (SVG) format is a method for creating vector graphics on the Web (see w3.org/ Graphics/SVG/). Like Flash, instead of plotting each point in a graphic, SVG data describes two points and then plots the path between them as a straight line or curve. Although it still lags behind Flash in browser penetration, SVG is natively supported in Firefox, Safari, and Chrome. The holdout is Microsoft’s Internet Explorer, which will not have SVG support until version 9.
