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 4.2.2 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:
- Fork this repository
- Clone your repository to a local directory
- Create a branch called update-version in your repository
- Run
bundle exec rake d3:update_version
- Create a commit stating the version you updated to
- Push to your repository
- Create a pull request
I will then merge and release a new version of the gem.
