arbor-rails

Note: This gem won't work properly in production mode as there are some weird pathing issues in arbor.js. Until it's fixed, might I recommend d3_rails?

This gem provides Arbor.js for your rails application. Add it to your Gemfile:

gem "arbor-rails"

And then inside app/assets/javascripts/application.js add the following:

//= require arbor

If you want to use Arbor tweening, you can also add:

//= require arbor-tween
