Diagram as a code

1. Diagram as Code: Automating
Visualization with Python

2. Introduction to Diagram as Code
Definition: Diagram as Code (DaC) is an approach to creating diagrams using text- based descriptions;
utilizes specialized languages like Graphviz, Mermaid, PlantUML, to define diagrams programmatically.
• Importance of visual representation in architecture design
• Briefly introduce Python as a tool for DAC

3. What is Diagram as Code?
Diagram as Code (DaC) is an approach to creating diagrams using text- based descriptions; utilizes specialized languages like Graphviz, Mermaid,
PlantUML, to define diagrams programmatically.
.
Supports main major providers including: AWS, Azure, GCP, Kubernetes, Alibaba, Oracle.
Other tools used: havai.io, Draw.io, Diagramgpt
Advantages of Diagram as Code
 Version Control: Diagrams are treated as code, allowing for precise versioning, collaboration, and change tracking
using tools like Git.
 Precision and Control: Users have granular control over diagram elements, layout, and styling, ensuring accuracy
and clarity in visualization.
 Scalability: DaC facilitates scaling of diagrams to accommodate changes in complexity, making it ideal for
evolving projects.
 Automation: Integration with CI/CD pipelines automates diagram generation and updates, reducing manual effort
and ensuring consistency.
 Collaboration: Teams can collaborate seamlessly by editing diagrams directly through code, fostering transparency
and efficiency.

4. Use Cases of Diagram as Code
•Software architecture diagrams
•Network topologies
•Business process flows
•Infrastructure as Code (IaC) representations

5. Using Python to create Architecture Diagrams
• Demonstrate how to create architecture diagrams using Python:
• Define components and connections using code
• Generate diagrams programmatically
• Customize diagrams with styles, colors, and labels

6. Conclusion
• Diagram as Code provides a structured, version-controlled approach to diagram creation, offering precision, scalability, and
automation advantages over other tools.
• Embrace DaC to streamline diagramming processes, enhance collaboration, and drive innovation in your projects.
