Types of Graphs
Explore the different types of graphs including directed, undirected, weighted, unweighted, cyclic, and acyclic. Understand their characteristics, uses, and how to implement them in JavaScript to solve real-world problems.
Graphs can be classified into different types based on how their edges behave. The most common classifications are:
Directed vs. undirected
Weighted vs. unweighted
Cyclic vs. acyclic
Directed graphs
A directed graph, or digraph, is a graph in which each edge has a direction. This means the connection goes from one vertex to another in a specific direction.
For example, if there is an edge from A to B, that does not automatically mean there is an edge from B to A.
A directed graph can be shown like this:
When directed graphs are useful
Directed graphs are used when relationships are one-way. Some common examples include: ...
