There are, of course, a plethora of choices for doing graphing in Ruby

I don't know if it is the best, as I've not tried too many other
libraries, but the ruby interface to the R-language, rsruby (
http://rubyforge.org/projects/rsruby/ ) is very powerful.

I think the large number of users and maturity of the R project makes it
one of the "best" packages for producing statistical/mathematical type
charts, but of course they tend to look a bit more "scientific" than
those produced by Gruff ( http://nubyonrails.com/pages/gruff ) for
example.
Hope this helps,
