title: Applying animation on a circular chart
body: <p>I have built a circular graph very similar to this example in paintcode:</p>

  <p>I have successfully drawn out the control on my iOS view with ease, but now I would like to animate the graph so that it begins at 0 and eases towards the specified angle. Basically the animation should look like the first two seconds of the video in the URL above.</p>
  
  <p>What is the best way to go about this type of animation?</p>
  
  <p>FYI: I am working in C#/Xamarin but I am not fussy on syntax at all, so an Objective C or Swift example will do just fine.</p>
