title: set the center of a embedded map (google map) to a specific location
body: <p>I'm trying to use this map in a website and I am using the next piece of HTML code to add it.</p>
  
  <pre><code>&lt;iframe src="https://www.google.com/maps/d/embed?mid=zkqAm4_X6ia8.kj6iIDUiDRdc&amp;hl=es" width="640" height="480"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>My problem is that I want the embedded map to show the Utrecht area only, but I can't figure out how to change the center of the embedded map. I know that the parameter z= will set the zoom level. I've tried the center= parameter as specified in the documentation, but it does not seem to work</p>

  <p>Thanks in advance!</p>
