Charts in Rails 4 application

Hi, Somebody advice me to find a better solution to implement charts in my Rails application. Which one is better 1) High charts 2) Fusion Charts 3) Open flash Charts                      i want to know whether these are free charts or paid service ? also pls let me know whether Open flash Charts can be used in Rails 4 application. (compatible)

Thanks.

Also consider D3? http://d3js.org/ It’s an open source html5-based javascript visualisation library.

There’s a gem here: https://github.com/logical42/d3_rails

Either use D3

https://github.com/logical42/d3_rails

Or,

https://github.com/winston/google_visualr

for Open source.

Both are paid

  1. High charts
  2. Fusion Charts
