My basic understanding of the garbage collectors in use by the various Ruby runtimes is that they all search for objects from a "root" memory object. If an object cannot be reached from this root, then it is collected.

I am also interested in generating vector graphics with Ruby. One thing 
I have peeked into is Cairo which advertises Ruby bindings. Cairo itself 
seems to be widely used and is intended to support multiple back ends 
including SVG.

Cairo is used by Shoes and Gnome. The Ruby bindings are called rcairo 
but the api docs are mostly in Japanese.
