Circular dependencies are problematic. To understand why, consider the following example.

Let's say we have five packages (A, B, C, D, and E) with the following dependencies:

• A depends on B and C
• C depends on D and E
• E depends on A

To illustrate these graphically, we can create a diagram where we can use an arrow notation to indicate dependencies between components. The direction of the arrow indicates the direction of the dependency.
