Hello! I created the sequence chart below to depict a scenario of interaction between a library patron and the new Thrive University (TU) library system.

Scenario: User Registration

Description: A new student, Alice, registers with the UT library system for the first time.

Explanation:

1. User (Alice): Initiates the registration process by sending a registration request to the system.
2. System: Validates the request and generates a unique user ID for Alice.
3. System: Sends a confirmation message to Alice with the assigned user ID.
4. User (Alice): Receives the confirmation and logs into the system using the provided credentials.

Could you help me create a Dataflow Diagram for this scenario? Thank you in advance!
