Class Diagrams

​

What are Class Diagrams?

​

Creating Your First Class Diagram

1. Launch DinoAI: From Code IDE, access DinoAI to start creating diagrams.
2. Use a Simple Prompt: Tell DinoAI what kind of Class Diagram you want to create. For example:

- "Create a mermaid class diagram showing my data model classes with attributes and methods"

- "Generate a mermaid class diagram for my dbt™ transformation logic with class relationships"

- "Build a mermaid class diagram showing my data pipeline components and their interactions"

3. Get Your Diagram: DinoAI will generate a complete .mmd file with proper Mermaid syntax.
4. Preview Your Work: Click the eye icon (👁️) to preview your diagram in real-time as you edit.
5. Iterate and Refine: Modify the generated .mmd file directly, or ask DinoAI to make specific changes.
