Apply the concept of a directed graph (digraph) by creating a visual representation with a neat diagram.

Sure, I can help you with that. Here are the steps to create a visual representation of a directed graph:

1. Start by defining the nodes or vertices of the graph. These are the entities or objects that you want to represent in the graph. For example, let's say we have four nodes: A, B, C, and D.

2. Next, determine the directed edges or arcs between the nodes. These represent the relationships or connections between the nodes. For example, let's say we have the following directed edges: A -> B, B -> C, C -> D, and D -> A.

3. Now, draw a diagram with circles or dots to represent the nodes. Label each circle or dot with the corresponding node name (A, B, C, D).

4. Draw arrows to represent the directed edges between the nodes. For example, draw an arrow from A to B, indicating that there is a directed edge from A to B. Similarly, draw arrows for the other directed edges.

5. Finally, you can add any additional information or labels to the diagram, such as weights or labels on the edges, to provide more context or details about the graph.

By following these steps, you can create a neat visual representation of a directed graph using a diagram.
