+ <p>
+ This example demonstrates how to provide AutoComplete suggestions for
+ an address calling Google's Geocoding Service.
+ </p>
+ <p>
+ Geocoding is the process of converting addresses into geographic
+ coordinates. The <a href="https://developers.google.com/maps/documentation/geocoding/">Google Geocoding API</a>
+ provides a direct way to access a geocoder via an HTTP request.
+ </p>
+ <p>
+ Google's Geocoding Service returns a JSON object literal. The service does
+ not provide a JSONP API. AutoComplete cannot use that object
+ directly for security reasons. So the workaround is calling the service
+ using YQL as source.
