title: How to change color and size of pie chart's default labels in Google Image Charts?
body: <p>Is it possible to change color and font size of default pie labels (in this simple example: "Hello" and "World") in Google Image Charts API? I've searched the documentation but I can't figure out how to do it...</p>
  
  <p>Example code:</p>
  
  <pre><code>https://chart.googleapis.com/chart?cht=p3&amp;chd=t:60,40&amp;chs=250x100&amp;chl=Hello|World
  </code></pre>
