It has been described as "the global mapping of everybody and how theyre related". The term was popularized at the Facebook
What is a Social Graph?A Social graph can be extremely complex and models relationshipsbetween – either inside or outside the enteprise – OR both!
What is a Social Graph?People, connected. Or further, ‘social objects’ connected.• People are connected to each other directly and indirectly.• The way they are connected varies. It could be through work, friendship, common interests, etc.• More importantly, there is something common between the people that are connected.

Some Characteristics of a graphMulti-relational graphs are the foundation. These are graphs whererelationships are described in more than one way.• Strong Ties and Weak Ties• Centrality – Defining people who are highly connected• Degree – How many people can this person reach directly?• Betweenness – How likely is this person to be the most direct route between two people in the network?• Closeness – How fast can this person reach everyone in the network?• EigenVector – How is this person connected to well connected people?
