Facebook like check

I've found an interesting app . This fb-app get all likes from any fanpage and sort it by mass and country!

My question:

how do these app get the data from the graph api ?

First: get the fanpage-object no access token needed

https://graph.facebook.com/cocacola/

{
   "about": "The Coca-Cola Facebook Page is a collection of your stories showing how people from around the world have helped make Coke into what it is today.",
   "checkins": 146,
   "description": "Created in 1886 in Atlanta, Georgia, by Dr. John S. Pemberton, Coca-Cola was first offered as a fountain beverage at Jacob's Pharmacy by mixing Coca-Cola syrup with carbonated water. 

Coca-Cola was patented in 1887, registered as a trademark in 1893 and by 1895 it was being sold in every state and territory in the United States. In 1899, The Coca-Cola Company began franchised bottling operations in the United States. 

Coca-Cola might owe its origins to the United States, but its popularity has made it truly universal. Today, you can find Coca-Cola in virtually every part of the world.

Coca-Cola Page House Rules: http://CokeURL.com/q28a",
   "founded": "1886",
   "is_published": true,
   "location": {
      "street": "",
      "zip": "",
      "latitude": 48.886763644968,
      "longitude": 2.2428464993582
      },

  "website": "http://www.coca-cola.com",
  "were_here_count": 0,
  "category": "Food/beverages",
  "id": "40796308305",
  "name": "Coca-Cola",
  "link": "https://www.facebook.com/coca-cola",
  "likes": 58345623, 
  "cover": {
     "cover_id": "10152037156953306",
     "source": "http://sphotos-b.ak.fbcdn.net/hphotos-ak-ash4/s720x720/602289_10152037156953306_1443207674_n.jpg",
     "offset_y": 0
  }
}

second: get the likes from the facebook object:

https://graph.facebook.com/cocacola/likes?access_token=xxxxxxx

now i will receive all fan-page which "cocacola" like, but i need all users which like cocacola!

Maby its only possible with FQL Query ?
