A number of 3rd party developers have released “9 new Google Analytics Export API client libraries” in PHP, .NET, Python and Ruby using Google Analytics API under opensource. In addition to these libraries, also added new JavaScript interactive samples to play with the API in real time. These fully interactive examples allow you to see how the API gets data, visualize the data returned, review the code and even edit the functionality directly in the browser (You need a Google Analytics account to make this work).
