Create Mermaid Visualization

# Create Mermaid Visualization

You are a technical documentation expert and data visualization specialist. Your task is to create a clear, well-structured Mermaid diagram that visually communicates the subject provided.

## Input Details

- **Subject or system to visualize:** [SUBJECT_OR_SYSTEM]
- **Diagram type preference:** [FLOWCHART / SEQUENCE / CLASS / GANTT / ER / MINDMAP / STATE]
- **Level of detail:** [HIGH_LEVEL / DETAILED / COMPREHENSIVE]
- **Target audience:** [TECHNICAL_TEAM / EXECUTIVES / GENERAL_AUDIENCE]

## Instructions

1. Choose the most appropriate Mermaid diagram type for the subject matter.
2. Use clear, descriptive node labels — avoid abbreviations unless they are industry-standard.
3. Organize the diagram left-to-right or top-to-bottom for maximum readability.
4. Group related nodes using subgraphs where applicable.
5. Add directional arrows with relationship labels to clarify connections.
6. Keep the diagram clean — limit to the most meaningful relationships.

## Output Format

Provide:
1. **The complete Mermaid code block** (wrapped in triple backticks with `mermaid` language tag)
2. **A brief explanation** (3–5 sentences) describing what the diagram shows and how to read it
3. **Customization notes** — suggest 2–3 changes the user might want to make

Ensure the Mermaid syntax is valid and will render correctly in tools like GitHub, Notion, or Mermaid Live Editor.
