ELI5: Explain Like I'm 5

social graphs

Social graphs are like maps of the world we live in, but instead of showing land, they show the relationships between people. They show who knows who, who is friends with who, who works with who, and so on. Everyone is represented by a dot on the graph and the lines between them show the connections between people. By looking at the graph, you can get a better understanding of how people are connected to each other.
