title: Add Effect to Highlighted Area Using jQuery Map Highlight Plugin
body: <p>I have an interactive venn diagram using the jQuery Map Highlight Plugin: <a href="http://jsfiddle.net/keith/REyPv/2/" rel="nofollow">http://jsfiddle.net/keith/REyPv/2/</a></p>
  
  <p>I'd like to make the initial highlighted item pulse or glow, because users have commented that they didn't know the diagram was interactive. I've tried adding fade or animate in jQuery but couldn't get it to work. And I think I'd only want the first highlighted item to glow, and not the others once the user starts interacting with it.</p>
  
  <p>Also I'm not sure if I'm highlighting the initial item correctly because I'm repeating code below it, so if there are any suggestions on doing that better I'd appreciate it.</p>
