Can anyone provide me a simple graph example on ruby

Say I have a table with two columns like this :

Age Number of people

21-40 48
41-60 22

Can anyone tell me, STEP BY STEP how to get this data in a graph
(line-graph) in ruby by any tool or gem.

Just read the API, it’s not very complicated. Google creates images
for you, you just use an url in an image_tag with some variables
added. There’s also a wrapper for it:
