a social network data visualization based on a model that is based on "mobile particles that randomly bounce off each other". this novel model fits with empirical data to naturally reproduce the community structure, clustering & evolution of general acquaintances & even sexual contacts. the different colored (blue, green, purple, orange) nodes represent students in different grades. links between nodes are drawn when a student nominates another student as a friend. in the recent study, physicists developed a novel model to describe this social network based on rules governing physical systems.
