The point of an infographic is to inform readers of it information in a new and creative way, this can work on standard information we already know or more unusual data that most are not known to. We were suggested to choice something usual, and while I was originally tempted to do one heavily themed on movies, I felt that was still a to standard and wanted something that would draw to the idea.
Thus, "The Beginner's Guide to Vampire-Slaying" was born, I gave it the really long title, because those always seemed to appear alot in old war pamphlets, those were one of my inspirations.
Another was gaming, a common occurence in games is to pick up an item and then you are given a bit of information with it, my little item bar to the left was created from that idea. Also weak points and areas of strength come up alot in boss fights and to a vampire slayer that's what a vampire is, the boss you need to defeat through being aware of such things.
