The code:
https://github.com/Slober3/Ostats-Ogame

It uses the public API
It's utilizing the high scores API and the players API
After it received the data it will upload that data to a MysqlDB this data is then used for creating a graph.
Nothing more nothing less the update interval is constant and is decided by the cronjob placed on the write.php
