It really kind of depends on what you want to do with the SVGs. They can cover topics such as icons, animations, UI, charts, reports, and so on. Just about anything you can imagine using a vector image instead of a raster applies. Many javascript libraries already exist to cover many of the usual situations. You can look into those and play with them to figure out where your interests lie.

And this isn't limited to web technologies and browsers.
