Ruby charting library?

I need to display some charts/graphs based upon user inputs on my web
aplication built using Ruby on Rails. Are there any charting libraries
out there that I could use with ROR for displaying simple bar, line and
pie graphs?

Hi Gerardo,

You can check the next libs out:

  • chart.js (which is probably one of the most popular chart framework)
  • lazy_high_charts (ported on rails. Not so nice and cool but fun and
    easy to use)
