What type of network diagram includes arrows indicating direction?

A directed network diagram is characterized by the inclusion of arrows that indicate the direction of relationships between nodes (or points). Each arrow in this type of diagram shows the flow from one node to another, which is essential for understanding how various elements in the network are interconnected. In directed networks, particularly in contexts like flow networks or transportation routes, it's crucial to know not only if a connection exists but also the direction in which it operates.

This directional aspect is significant for accurately modeling scenarios where the direction of movement or influence matters, such as traffic flow, data transmission, or any interactive system where entities work in a specified sequence or pathway. Understanding this characteristic helps in analyzing and interpreting the behavior of the network effectively, making it a fundamental concept in the study of graph theory and network analysis.

In contrast, other types of networks, such as weighted, undirected, or loop networks, do not primarily focus on directionality. Weighted networks incorporate values (weights) on the edges, undirected networks signify connections without direction, and loop networks involve cycles but without emphasizing directional flow.
