I've developed a ruby gem called GoogleVisualr for use in ruby/rails
projects, and you can find it at
https://rubygems.org/gems/google_visualr.
Source is also available at
https://github.com/winston/google_visualr.
To quote myself:
"This Ruby gem, GoogleVisualr, is a wrapper around the Google Chart
Tools that allows anyone to create the same beautiful charts with just
Ruby; you don't have to write any JavaScript at all."
Hope this is helpful to any rubyists in this group, and feel free to
fork the repo!
Thank you!
Cheers,
Winston
