One of the features I like about RubyMine is the gems dependency graph. This graps shows you all explicit/implicit dependencies of gems defined in your Gemfile. In this short tutorial, I’ll show how to generate this graph with Bundler.

In order to generate graph, you need to change directory to the app folder where the Gemfile file resides then use command:
1 2 3
If there is no errors, you should see the image file path in the output.
Open it up and you’ll see something like this for a stock Rails 4 app:
