Each plotted point is called a vertex (the plural of this is vertices), and the lines connecting them are called edges.

Graphs can also be used to represent a kind of connection between two cities or stations, where stations can be represented by vertices and the route can be represented by edges. On social media, even friends can be connected in the form of graphs where each person can be represented by vertices and...
