Check this out – it’s a web applet that takes a text and constructs the social relationships between the names mentioned in the text. Originally it was meant for mapping out novels, but someone has run the program on the text of the New Testament:

Of course Jesus is at the center – but it’s interesting to see how the other folks in the NT relate.
Thanks to ESV Bible Blog for the pointer.
