WebGraph (discrete mathematics) A graph with six vertices and seven edges. In discrete mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related". The objects correspond to mathematical abstractions called vertices (also called nodes or ... Webval newGraph = graph. mapVertices ((id, attr) => mapUdf (id, attr)) These operators are often used to initialize the graph for a particular computation or project away unnecessary properties.
