Google interactive charts (http://code.google.com/apis/chart) are heavily dependent on javascript (the entire charts package is one big javascript library) and won't work if javascript is disabled. On the contrary Google Image Charts (http://code.google.com/apis/chart/image/) are rendered as plain images, hence they will work if javascript is disabled, although obviously screen readers won't be able to understand the contents of the image.
Screen-readers aside, your best option could be to fallback to Google Image charts when javascript is disabled, and use Google interactive charts otherwise. Note however, that the two have different APIs, so supporting both and falling back from one to the other might not be simple. -R.
