Graphs consist vertices edges from "summary" of Introduction to Graph Theory by Douglas Brent West
A graph is a mathematical structure that consists of two main components: vertices and edges. Vertices are the points or nodes in a graph, while edges are the connections between these points. In other words, a graph is a collection of points joined by lines. Vertices are typically represented by circles or dots, while edges are represented by lines or arcs connecting these points. Vertices can be thought of as the entities in a graph, such as cities in a map, while edges represent the relationships or connections between these entities, such as roads connecting the cities. In a graph, each edge connects two vertices, and these vertices are said to be adjacent to each other. The number of vertices connected by an edge is k...
