IPA: /ˈsʌbˌɡræf/
KK: /sʌbˌɡræf/
A part of a larger graph that includes some of its points and connections.
In computer science, a subgraph can be used to analyze specific relationships within a larger dataset.
Subgraph → It is formed from "sub-" (meaning under or below) and "graph" (from Greek "grapho", meaning to write or draw). A subgraph refers to a smaller graph that exists within a larger graph, essentially a graph that is 'under' or part of another.
Think of a smaller drawing ('graph') that exists 'under' ('sub-') a larger one — that's what a subgraph is.
