Have you worked with C4 diagrams?

C4 diagrams are a method of visualizing software system architecture, developed by Simon Brown. They help illustrate the system at different levels of detail:

• Context — the overall picture of the system and its environment, interactions with external users and systems.
• Containers — the main applications or services within the system, their responsibilities, and interactions.
• Components — internal parts of containers, modules, or services they consist of.
• Code — a detailed level showing classes and their relationships (usually UML).

Experience with C4 typically involves creating such diagrams to understand and communicate architecture, which helps the team and stakeholders better understand the structure and interactions within the system.
