This page contains a collection of SVG images which illustrate a wide range of SVG's capabilities. I'll let the images speak for themselves. When relevant, the text below an image / shape is a link to the text explaining how to draw that shape, or achieve that effect etc.
NOTE: If you cannot see any of the images below, your browser is not able to show SVG. You might be able to fix that by installing the Adobe SVG Viewer.
