title: Obtaining the center of a WKT polygon
body: <p>I'm using pandas, and a dataset I obtained has a location column in a WKT format. For example:</p>
  
  <p><code>hospital.get_value(1,'WKT')</code></p>
  
  <pre><code>POLYGON ((-58.4932 -34.5810,-58.4925 -34.5815,-58.4924 -34.5817))
  </code></pre>
  
  <p>There's a lot more points and with bigger precision in this example, but I shortened it for illustrative purposes. Also, I don't know whether it is a WKT or just a string. How do I obtain the center of this polygon so I can use it as a coordinate? Thanks in advance.</p>
