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.

You can get an idea of some of the capabilities of the R plotting engine 
here:

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,

Chris
