D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS.

d3-rails provides D3 for Rails 3.1 and higher.


d3-rails comes with version 5.7.0 of D3.js. The d3-rails version will always mirror the version of D3. If you need a newer version of d3-rails, see section Development (below).


Add this line to your Gemfile:

gem "d3-rails"

Please note that D3 is provided via the asset pipeline and you do not need to copy their files into your application. Rails will get them from d3-rails automatically.

Then add it to your manifest file, most probably at app/assets/javascripts/application.js:

//= require d3


If you need a newer version of d3, please do the following:

  1. Fork this repository
  2. Clone your repository to a local directory
  3. Create a branch called update-version in your repository
  4. Run bundle exec rake d3:update_version
  5. Create a commit stating the version you updated to
  6. Push to your repository
  7. Create a pull request

I will then merge and release a new version of the gem.
