If you often sit and wonder how your iPad data plan here in the U.S. compares to the rest of the world, you can wonder no more. As it turns out, AT&T isn’t the worst offender when it comes to overpriced data plans for the iPad, and the cheapest prices are probably somewhere you’d never guess.

Engadget is reporting that data visualization firm Tableau has a swanky new chart comparing the data plan costs for the iPad around the world (full chart is below). While AT&T users here in the United States love to complain about their not-so-favorite telco, in this case they’re actually not the worst offender, with a minimum cost of $12.50 per gigabyte.

The top spot is held by France’s carrier Orange, who charges a whopping $25.47 per gigabyte for iPad data, trailed closely by Mobistar in Belgium and Luxembourg. Netherlands carriers Vodafone and T-Mobile fall into the fourth and fifth positions with $19.59 and $19.56 per gigabyte, respectively, followed by our own AT&T.

So where do you have to travel to get the cheapest iPad data around the world? Turns out it’s Singapore, with a total bargain at only 51 cents per gigabyte. Before you get excited, PC Magazine notes that that figure is “a tad misleading,” given that it’s based on carrier SingTel’s cheapest pre-paid data plan which gives you unlimited access for only three days.

But hey, we’ll take what we can get, right?
