Data visualization artist Eric Fischer has created some fantastic maps of human trends based on millions of tweets. He analyzed the tweets with location data for where they were posted, then looked at the posting history for each account. If you had been posting in one region for longer than a month, you were categorized as a local, other wise as a tourist.
When mapping out each tweet's location using red dots from tourist and blue ones for locals, Fischer was able to discern the hot spots for tourist in a heat map fashion. We all know where the tourists flock and where to avoid, so a more interesting feature in the interactive map is to look at the hot spots for locals. What streets are the hottest in each neighborhood, or what areas are "dead zones" with not a lot of things going on?
