title: Creating graphs for both WP7 & WP8
body: <p>My question is really: Is there an easy way to create graphs in windows phone? (Either in-built or for free)</p>
  
  <p>Could you tell me of any using statements I need to add</p>
  
  <p>Links would be helpful (I couldn't find many myself)</p>
  
  <p>And a basic how-to would be excellent!</p>
