I guess it depends on if you are sure you will use it. You can load the jsapi script in the first loading, and then load the visualization api later. It is up to you, eventually. Loading more code in the initial loading slows the first time you see the page, naturally. > > How do I 'Make sure the DOM is ready when you call google.load with > the callback option because it will try to append an element to the > DOM'. ? You can use the page onLoad event.
