I understand that there are people in the world who have to hide their private data for fear of gov't persecution or extreme judgement from family and their peers.

That's not the case for me, my Facebook data is useless. If they kept it, it wouldn't harm me in any way. It's not super secret, or very interesting stuff. So why not give it to them to visualize in an interesting way?

I do completely agree here. I don't know why people prefer hiding their email IDs and friends lists, comments they have made and things they liked. Having said that, I might have to make my privacy settings more strong if the Facebook Graph Search turns something like http://news.ycombinator.com/item?id=5100679
