### Analyzing the Statement

1. **Understanding Use Cases**: Use cases are indeed graphical representations used in software engineering and system design to illustrate interactions between users (or external actors) and the system. They can take the form of diagrams or written narratives.

2. **Perspective of External Actors**: The statement specifies that use cases describe the flow of events *from the perspective of an external actor*. This is a crucial aspect of use cases, as they are primarily concerned with how users interact with the system rather than internal processes or functionalities.

3. **Verifying the Concept**: By definition, use cases help identify the functional requirements of a system based on how it will be used by external actors. They typically outline the 'who', 'what', and 'how' of a system's interaction with the users.

### Conclusion

Based on the understanding of what use cases are and how they are designed to represent the interactions from an external perspective, the statement is **True**.

### Final Answer
**True**
