That's a bit more than I want to bite off right now. However, I recently saw another monk here refer to the module Graph::Easy::Parser. You may want to take a look at it. It will help you turn your list of edges into a graph. I don't know about filling in missing nodes or not, but I wouldn't be surprised if some tools for that are in there as well.

Once you start looking into the Graph modules, you'll see that they have ways to create HTML, ASCII, and many other useful output formats. Try going to www.cpan.org and getting some of the Graph modules and work through the examples. Then you'll be able to ask smaller questions......8^)

Hope this helps a little...
