title: Only text after clicking the example for directions API
body: <p>Instead of displaying a map after clicking one of the Example Directions Requests
  on the following API directions tutorial <a href="https://goo.gl/rnFLAo" rel="nofollow">https://goo.gl/rnFLAo</a> only text is being displayed at the opening page.
  I do have a functioning API key for a browser.
  What's going wrong?</p>
