title: Is data sent to Google when using the Google Visualisation API?
body: <p>I am developing a web app for a client and I want to use the Google API's to draw some nice graphs.</p>
  
  <p>The client has some sensitive data and has raised some concerns about security, specifically, they do not want their data "going to Google".</p>
  
  <p>There are 2 options or API's for generating charts. The Chart API, where you build a URL and submit to Google so that it can generate a graph image - obviously the client data IS going to Google so this option is a no no.</p>
  
  <p>The second option is to use the Visualisation API. As far as I am aware, the code to generate the visualisation is downloaded from Google, but the data used to build the output never leaves the browser, and therefore is "safe" to use with sensitive data. Is this an accurate description?</p>
  
  <p>I have looked through the Google API documentation to try and answer my question but cant seem to find a definitive answer.</p>
  
  <p>Please advise.</p>
