📦 What is Diagrams?
Diagrams is a Python library that lets you draw cloud system architecture diagrams using code instead of drag-and-drop tools.
🏗️ Infrastructure as Code Philosophy
Just like Infrastructure as Code (IaC) manages infrastructure through code, Diagrams as Code creates architecture diagrams programmatically.
☁️ Multi-Cloud Support
Diagrams supports all major cloud providers (AWS, Azure, GCP, Kubernetes), on-premise solutions, and SaaS services.
🔗 Simple Syntax
The library uses intuitive Python syntax with operators like >> for data flow, - for connections, and list notation [] for parallel components. Clusters group related resources together.
🎉 Browser Magic with viz.js!
The Diagrams library generates Graphviz DOT format, which normally requires a native
binary. We're using viz.js (Graphviz compiled to WebAssembly) to render
the diagrams directly in your browser! The Python code intercepts the graphviz.Digraph class to capture DOT
output.
Icon loading: Cloud provider icons are fetched from the diagrams GitHub repository, converted to base64 data URIs, and embedded directly into the SVG.
💡 Real-World Use Cases
• Document system architecture in your repository
• Auto-generate diagrams from infrastructure code
• Create visual documentation for technical proposals
• Maintain architecture diagrams alongside code changes
• Generate diagrams in CI/CD pipelines
🚀 Getting Started Locally
To use the Diagrams library in a local Python environment:
pip install diagrams
You'll also need Graphviz installed on your system. Visit diagrams.mingrammer.com for full documentation and installation instructions.
