Answer 1

Too bad that you are asking for an implementation of a directed unweighted graph rather than for a straight-use. Otherwise, I will suggest you to use a readily-made framework for almost anything that relates to network/graph called JUNG2. You can use it either in GUI or in non-GUI mode. It will save you a lot of time tinkering. Following is its tutorial link:
