Social graph
Example of a social graph.
The social graph is a term coined by Mark Zuckerberg, founder of Facebook, which originally referred to the social network of relationships between users of social networking service provided by Facebook. This term has been described as "the global map of the whole world and how they are related." The term was coined in the Facebook f8 conference on May 24, 2007, when it was used to explain that the Facebook platform would benefit from social graph, taking advantage of the relationships among individuals that Facebook offers to provide a rich online experience.
The social graph is an abstract concept that describes the relationships between people online, as opposed to the idea of a social network, which describes relationships in the real world. The two concepts are very similar, but there are some minor differences. For example, the social graph is digital and, more importantly, it is explicitly defined by all the connections in question.
