This is a 1.0 project I completed a while ago but never announced/promoted.
It's a free PHP wrapper for Highcharts that is licensed by Gravity.com and released using the Apache 2.0 license.
I created this wrapper to make it easier to create Highcharts objects in my PHP projects. I have employed it successfully in Zend FW and in ToroPHP (http://toroweb.org/)
