This website has an image that shows a graph for the player's ranking (see bottom right). I assume the value is entered into a database and then a script produces the graph automatically. Do you know of any such scripts? Currently my site scrapes the latest ranking from an official website and then stores it within a text file. Can something like that graph be implemented with such a system?
It can be using the PHP GD library. Its fairly complex though, and if you aren't very good with PHP....I'd pay someone.
