No matter how much you zoom out, The Internet Map is bigger than you think. Developed by Ruslan Enikeev, it includes the 350,000 largest sites on the web! I'm pretty sure the different colors represent different languages. Neatorama is the medium-sized blue dot between Boing Boing and Buzzfeed, to the left of reddit. There's a search field in case you want to find a particular site.
Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other.
