Animating Regular Expressions With Python and Graphviz

Regular expressions have a bad reputation. It seems like whenever they’re mentioned, it invokes images of terrifying walls of text that look like absolute nonsense. For example, this is a commonly-cited regex for validating email addresses: (?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?
