SVG has a few basic shapes available that in most cases are easier to work with than the equivalent path data. Basic shapes include rectangles, circles, ellipses, lines, and polygons. With these basic shapes, simple programs don't have to know how to form the correct Bézier curves just to create a circle. For example the following are equivalent:
Because SVG is a XML based file format, it can use features from other XML based things. Objects can have clickable links just like in HTML. So one can theoretically make a whole website out of SVG files. Matter of fact, one can have SVG inside the XHTML file by the use of XML namespaces. In fact I'll do just that right here.
Another cool feature of SVG is the embedding of images. Normally images are just referenced in SVGs just like in HTML, but there is a thing called
data URI. Data URIs is a way to embed data in a place were there would just be a reference. This URI then can be placed in the href attribute of the anchor element for both HTML and SVG.
There's this online program that can make basic SVG files right inside of your web browser. The program is called SVG Edit. It would be interesting to see what you could make with this.
