How to write in HAML template javascript loop with data from controller?

I am getting from controller data in global variable @controller_data which contains array.

I am also using Highcharts, where is used following procedure for rendering data in charts:

data = [{
           y: 55.11,
           color: colors[0]
         }, {
           y: 21.63,
           color: colors[1]
         }, {
           y: 11.94,
           color: colors[2]
         }, {
           y: 7.15,
           color: colors[3]
         }, {
           y: 2.14,
           color: colors[4]
         }];

I am using HAML template system. How to fill out this Javascript array with data from controller?

Assuming that @controller_data is just a simple array of hashes, suitable for passing directly to JavaScript:

:javascript
  data = #{@controller_data.to_json};

Haml allows you to do string interpolation inside of content, including JavaScript Filters.
