The views per week don't come from Google analytics, they're from an internal database. And yes, there is more than just the previous week last I checked. I think it goes back to early 2012. As far as accessing that data goes, it's unavailable at the moment, but you can write in to Special:Contact/general to request increased access to site metrics data. No promises on if/when that'll happen though.

Google Analytics is very much unavailable for wiki admins and likely will be for the foreseeable future. I tried getting access to it and miserably failed. It's already set up for Wikia, but unlike quantcast they don't offer the ability to show the data to individual wiki admins. You can always ask for Quantcast access though which has plenty of pageview data. You can't set it up yourself unfortunately.

As for a visitor, I think it's linked to someone's IP address. when I was trying to make something similar I defined a viewing session as pageviews made by a specific browser which were increased as they visited more pages. The session ended if they navigated away in the meantime, or if there was no activity for an hour. I think the more professional metrics sites do something similar.
