Graph

A series of dots connected to each other by a line.

Networking

A graph that has at least one pair of dots.

Vertex

Dots that connect a line.

Edge

The line connecting the two vertices.

Degree

The number of edges that connect it with another vertex.

Multiple edges

The connection between the two vertices is expressed through more than one edge.

Loops

Curved or circular edges that turn to the original corners.

Number of degree for each loop

Equivalent to two, namely clockwise and counterclockwise rotation.

Loop vertex pair

(a, a)

Multiple edges vertex pair

(a, b) and (a, b)
