btw. I think the prefered way of loading the vis packages is via VisualizationUtils.loadVisualizationApi(PieChart.package, ..., myCallback) instead of via the hostpage...so you can be sure that when the callback gets called the visualizations are ready to roll (this has been buggy before but is now fixed on google's servers).
