The Graph API is named after the idea of a "social graph" — a representation of the information on Facebook. It's composed of:
nodes — basically individual objects, such as a User, a Photo, a Page, or a Comment
edges — connections between a collection of objects and a single object, such as Photos on a Page or Comments on a Photo
fields — data about an object, such as a User's birthday, or a Page's name
Typically you use nodes to get data about a specific object, use edges to get collections of objects on a single object, and use fields to get data about a single object or each object in a collection.
Structure
We cover this fully in our Using the Graph API guide, but in general you:
use nodes to get data about individual objects
use edges to get collections of objects connected to a node, or to publish objects to those collections
use fields to specify which data you want included in responses
