title: Charts in Ruby on rails 3 web app
body: <p>I need to generate some charts and graphs in a Ruby on Rails 3 app.</p>
  
  <p>I have searched around for a gem to help me out and I have found <a href="http://code.google.com/p/gchartrb/" rel="noreferrer">gchartrb</a>, <a href="http://googlecharts.rubyforge.org/" rel="noreferrer">googlecharts</a> and <a href="http://nubyonrails.com/pages/gruff" rel="noreferrer">gruff</a>, but the first two seem to be too old to support Rails 3 (last commit is around 2008) and gruff <a href="http://railsontherun.com/2007/10/4/sexy-charts-in-less-than-5-minutes/" rel="noreferrer">I read</a> that it is not recommended because it depends on ImageMagick and RMagick. But this was also from the year 2007.</p>
  
  <p><a href="http://www.highcharts.com/" rel="noreferrer">HighCharts</a> also have nice looking charts, but I don't have much JavaScript skills</p>
  
  <p>So what gem or what approach would be best to have some bar/line/pie charts in a rails app?</p>
