What is your preferred way to produce charts in a Ruby on Rails 3 web application?

I know this question has been asked 3 years ago, so I was wondering is there anything new and/or better than it was 3 years ago.

Currently, I am using GoogleVisualr ( http://googlevisualr.herokuapp.com/ ) and I like it...it is simple and easy, but it lacks radar charts :(

So, I was wondering is there any other free and easy charting solutions? Javascript or flash is good for me, but I need to have radar charts.

Thank you Dorijan

Have you looked at d3.js?

Also found someone who has [shared] (https://groups.google.com/forum/m/#!msg/protovis/GsFB1l1Mo_g/geLerhwvbdQJ) their code to create radar graphs using protovis which still available.

Finally, someone else's [sample] (https://gist.github.com/1630683) of radar graphs using d3.

Check following code,

  <html>
      <head>
        <script type='text/javascript' src='https://www.google.com/jsapi'></script>
        <script type='text/javascript'>
        google.load("visualization", "1.0", {packages:["imagechart"]});
        </script>
        <script type='text/javascript'>
          google.setOnLoadCallback(drawChart);
          function drawChart() {
            var dataTable = new google.visualization.DataTable();
            dataTable.addColumn('number');
            dataTable.addColumn('number');
            dataTable.addRows([
              [100,10],
              [80,20],
              [60,30],
              [30,40],
              [25,50],
              [20,60],
              [10,70],
            ]);

            var chart = new google.visualization.ImageChart(document.getElementById('radar_div'));

            var options = {cht: 'rs', chco: '00FF00,FF00FF', chg: '25.0,25.0,4.0,4.0', chm: 'B,FF000080,0,1.0,5.0|B,FF990080,1,1.0,5.0',};
            chart.draw(dataTable, options);
          }
        </script>
      </head>
      <body>
        <div id='radar_div'></div>
      </body>
    </html>

I use and recommend Highcharts. It's not free, but it works well and has lots of features. Also, it's very well documented and has tons of working code examples on the site.

Development licenses (I believe) are free so you can try it out at no cost then pay only if you decide to use it. The price isn't too high either considering the time it saves.
