Great to see that this project is active :)

I love the idea about the Dependency Graph. I would also like to have diagram for all the dependencies. I understand that

1. it could be difficult to visualize it in the terminal
2. it is not appropriate to include any library rendering some graphical chart in this package

Goal

After a little research, it seems that the easiest way to generate some kind of relation diagram would be to use a dot file ( https://en.wikipedia.org/wiki/DOT_(graph_description_language) ) There are plenty of tools that can generate output based on the dot file. I don't think it is even necessary to generate the dot file itself by this package.

Output

A simple structure as output would be sufficient to generate a dot file. Or to do any other analysis if it is the case.
For example

[
  ['componentFoo', ['dep1', 'dep2'],]
  ['componentBar', ['componentFoo', 'dep2']],
  // ...
]

What now ?

I'm willing to do (or help with) the PR. It seems it might not be that straightforward because of the possible children containers. Any pointers would be appreciated.

What do you think ?
