What is Ruby Vector Graphics?

Ruby Vector Graphics (RVG) is an add-on library for RMagick
(http://rmagick.rubyforge.org). RVG is a facade for RMagick's 2D drawing
class, Draw. The RVG methods are based on the Scalable Vector Graphics
specification. See the RVG home page at http://rvg.rubyforge.org for an
example.
