@cronk005,
The issue seems to happen due to overriding of window.onload event. Changing it to jQuery ready / load should work fine in your case. Please find the sample project here. Please refer this stackoverflow thread for more info.

PS: dataPoints are hardcoded in sample-project as AJAX requests (php-service-http://globe-trekking.com/vg/charts/top_aircraft_data.php) gave 404 Not Found Error.
