Using a remote library when a local one will do is also a security risk. And though well-intentioned, forcing applications to automatically use the latest version of GVIZ could also be a security problem (not just a product management nightmare as I've pointed out elsewhere). The GVIZ libraries may be interacting with the greater application in ways the Google team hasn't foreseen, so forcing an update could cause problems Google's team hasn't seen.
But back to the original poster's point: competing javascript libraries from other companies allow you to run them in your preferred environment (which can be offline). Some of these competing products are free, and some of them are quite good. Google likes to have their customers hit their servers for everything they do, though, so I suspect this is part of their greater strategy. This can give them useful market intelligence, so I can see why they're reluctant to let it go -- Google is more about being an online business than a software dev firm. But if your application doesn't require an online connection, this just adds a point of failure without much benefit. >From my perspective, the best reason for downloading the libraries for "offline" use is the ability to control which version you're using. just my 0.02, On Jul 4, 7:25 pm, Riccardo Govoni ☢ <[email protected]> wrote: > Hi, > The most prominent reason for requiring an active internet connection is > that the visualization library is loaded dynamically by the client from > google servers whenever the client accesses a webpage using it.
