Generate SVG railroad syntax diagrams, like on JSON.org

Railroad-diagram Generator is a small library for generating railroad diagrams (like what JSON.org uses) using SVG, with both JS and Python ports. Railroad diagrams are a way of visually representing a grammar in a form that is more readable than using regular expressions or BNF. They can easily represent any context-free grammar, and some more powerful grammars. There are several railroad-diagram generators out there, but none of them had the visual appeal I wanted, so I wrote my own.
