I want to create graphs similar to those in Excel
(like bars) from a database using Rails.
the graphics should be displayed within a HTML page.
I think SVG might be an option. I have not used it
but maybe SVG is not the best option here.
it should work in all browsers. maybe later some
animations will follow.
are there any plugins or libraries that can help with
the creating 2D graphics ? I search raa and found an
old SVG library. but that was all.
has anyone used the RVG extension to RMagick ?
