title: PHP or Jquery for interpreting and formatting json data for polymaps?
body: <p>I'm pulling data from the Instagram API and caching it using php for use with a Polymaps application. My question is simple (but probably not simple) -- I've been approaching this from the standpoint that I should format my data in php and then make a json file I can use directly with polymaps. </p>
  
  <p>Would it be better to just cache the json file and use javascript to pull the information I need from it? </p>
  
  <p>Or is this mostly a matter of personal preference?</p>
