This project is using Ruby to build a high powered analytics dashboard website using Google Charts JavaScript library which is being hosted on GitHub Pages. Bootstrap and jQuery are also being used for a responsive designed mobile first website.
Another interesting technique that is being used is concatenation to build all the HTML 5 pages, which are then written to files via variable interpolation.
Ruby instance variables are being used for each HTML page via the instance_variable_get and instance_variable_set built in Ruby custom functions.
Fork and pull request. Simple.
