Badly translated from Russian
Mathematically speaking, the Internet is a two-dimensional map display of links between sites on the Internet. Each site is a circle on the map, its size is determined by the attendance of the site, higher attendance gives a larger circle. Transitions between the sites users form a connection, the stronger the connection - the closer sites "want to" sit near one another.
Map of the Internet is a snapshot of the global network at the end of 2011. It covers more than 350 000 sites from 196 countries and all domain zones. Information on over 2 million connections between sites combined them into thematic clusters. As might be expected, the largest clusters are formed by national sites, i.e. sites belonging to one country. For convenience, the sites related to one country have the same color.
