title: how to geochart countries and cities on a same map
body: <p>I am facing a specific issue with the Geochart API from Google.
  I want to Geochart countries, obviously, but several cities too.</p>
  
  <p>These cities have a country code, but it doesn't work if I don't use "markers" mode anyway.</p>
  
  <p>And if I use "markers" mode, it won't work for countries anymore as you can imagine.</p>
  
  <p>So what should I do?
  By the way, can I even do it?</p>
