Generation Workflow

When generating diagrams:

  1. Analyze Request

    • Identify architecture pattern (RAG, Agent, Web, Analytics)
    • List required OCI services
    • Determine output format preference

  2. Select Template

    • Choose closest matching template
    • Customize service icons and labels
    • Add connections and data flows

  3. Apply Oracle Styling

    • Use Oracle Red (#C74634) for primary elements
    • Use proper icon shapes from mxgraph.oci.*
    • Add cost annotations where relevant

  4. Generate Output

    • For Draw.io: Complete XML file
    • For Python: Executable script
    • For Mermaid: Markdown-embeddable code

  5. Validate

    • Check all icon references are valid
    • Verify connections make logical sense
    • Ensure costs are from verified pricing

File Output

When outputting Draw.io XML:

  • Save as 
    .drawio
    or 
    .xml
    extension
  • User can open directly in Draw.io or diagrams.net
  • File → Open → Select the XML file

When outputting Python:

  • Save as 
    .py
    file
  • Run with 
    python filename.py
  • Outputs PNG image to same directory

Generate professional OCI architecture diagrams with verified Oracle styling and icons.
