Scalable Vector Graphics (SVG) is a 2D vector image format based on an XML syntax.
The W3C began work on SVG in the late 1990s, but SVG only became popular when Internet Explorer 9 came out with SVG support. All major browsers now support SVG.
Based on an XML syntax, SVG can be styled with CSS and made interactive using JavaScript. HTML5 now allows direct embedding of SVG tags in an HTML document.
As a vector image format, SVG graphics can scale infinitely, making them invaluable in responsive design, since you can create interface elements and graphics that scale to any screen size. SVG also provides a useful set of tools, such as clipping, masking, filters, and animations.
