Node (graph theory)

The basic unit of a network — a point that can connect to other points. In a graph, everything reduces to two things: nodes and the links between them. A tree, a person, an airport, a web page can each be a node; what makes it a node is not what it is but that it can connect. On Pandora, a single tree or a local grove is one node in the network the Na'vi call Eywa.
