For me this makes no sense. Do you really want to ask Guice for each
single Node? Imagine each Node is immutable (as it should be if
possible) and contains its name. How do you plan to make Guice know
what's the name of the new Node?
I'm quite sure you're going to make your life harder this way. Simply
asking Guice for NodeFactory, EdgeFactory, and GraphFactory would IMHO
do all you need.

Don't let the dependent project know the implementations, let it see the
interfaces only (extract them to a third project).

Ideally, you should create only one injector and ask it for only one
object, which provides the root service you need. However, the world is
not ideal, so you may need child injectors, passing injectors around, or
whatever. That said, I'm not sure if I understood your question.
