A vertex, also known as a node, is a fundamental element in a graph that represents a point or object. In other words, it is a location or position in the graph where edges can connect.
An edge is a connection or link between two vertices in a graph. It can be represented by a line or arc and is used to show a relationship or interaction between the two vertices it connects.
Yes, a vertex can have multiple edges connecting it to other vertices in a graph. This can represent multiple relationships or interactions with other objects or points in the graph.
Endpoints are the vertices at the beginning and end of an edge. They are the points where the edge connects to the vertices and are important in determining the direction of the edge.
Vertices and edges are the two main components of a graph and are closely related. Vertices represent the objects or points in the graph, while edges represent the connections or relationships between the vertices. Without vertices, there can be no edges, and without edges, there can be no connections between vertices in a graph.
