title: Building a tag cloud in WPF
body: <p>I'm trying to build a tag cloud in WPF based on <a href="http://blogs.vertigo.com/personal/alanl/Blog/Lists/Posts/Post.aspx?ID=18" rel="nofollow">an existing implementation</a> [<a href="http://alanle.com/wp-content/uploads/2009/12/WPFTagCloud.zip" rel="nofollow">Download Source</a>]. I didn't understand completely the implementation and my problem is, that instead of having the FontSize binded to the number of items in a collection, I want to bind it to some other values contained in a class. So in this part here, </p>
  
  <pre><code>FontSize="{Binding Path=ItemCount, Converter={StaticResource CountToFontSizeConverter}}"
  </code></pre>
  
  <p>I want to bind the FontSize to something else. How do I do that? Where does ItemCount belong to?</p>
  
  <p>Thanks</p>
