Edward Tufte is generally considered the highest authority on information design. His book Envisioning Information is what you want to read (along with the rest of his writing). David McCandless who writes Information is Beautiful creates the sort of popular and fun types of info graphics that often don't need the complexity of attempting to be an info graphic at all. However, might be a good starting point for exploring different options/inspiration.
Sometimes the best way to start these things off is using the graph tool in Illustrator, inputting your data and seeing what comes out the other end. Then use that to inform how you want to explain the patterns you have discovered... Is it's really data heavy and you want some automation I have no idea where to start with that.
