Chapter 1: Graph¶
Graphs express entities (nodes) along with their relations (edges), and both nodes and
edges can be typed (e.g., "user"
and "item"
are two different types of nodes). DGL provides a
graph-centric programming abstraction with its core data structure – DGLGraph
. DGLGraph
provides its interface to handle a graph’s structure, its node/edge features, and the resulting
computations that can be performed using these components.
