It is possible that changes to the API could break existing code, though this happens infrequently (and is usually the result of a bug rather than a planned feature deprecation). Announcements concerning feature deprecation are typically made in this forum.
Currently, to the best of my knowledge, there is no limit on API requests for the Visualization API. In any event, such a limit would apply only to the number of requests made to Google's servers and not to the total number of charts you draw per page load (the interactive charts are drawn entirely in javascript - you load the API only once on the page and then draw as many charts as you like). As to whether it is a good idea to use the Visualization API or not, my opinion is that for the combination of versatility, simplicity of use, and cost, you can't beat the Visualization API. There are other tools which are, perhaps, more powerful or more flexible, but they are either more complicated to implement or you have to pay for them.
