Question

I’m reading the Terms of use which can be found here: http://code.google.com/apis/visualization/terms.html

But I do not see anything telling how Google use the data provided to generate the charts. Can someone be kind and enlighten me?

Answer 1

The Privacy Policy is likely to apply here. The relevant part should be:

Log information – When you access
Google services via a browser,
application or other client our
servers automatically record certain
information. These server logs may
include information such as your web
request, your interaction with a
service, Internet Protocol address,
browser type, browser language, the
date and time of your request and one
or more cookies that may uniquely
identify your browser or your account.

In combination with

Affiliated Google Services on other
sites – We offer some of our services
on or through other web sites.
Personal information that you provide
to those sites may be sent to Google
in order to deliver the service. We
process such information under this
Privacy Policy

Because you send the chart information with the URI and thus they will at least log it.
