Chapter 1: Graph¶
Graphs express entities (nodes) along with their relations (edges), and both nodes and
edges can be typed (e.g.,
"item" are two different types of nodes). DGL provides a
graph-centric programming abstraction with its core data structure –
provides its interface to handle a graph’s structure, its node/edge features, and the resulting
computations that can be performed using these components.
The chapter starts with a brief introduction to graph definitions in 1.1 and then introduces some core
