Talks - Tadeh Hakopian: Using Diagrams to Communicate Complex Ideas with Python

Good diagrams follow core fundamentals: hierarchy, structure, contrast, color, space, and variety

Python offers multiple libraries for creating diagrams:

• MinGrammar
• Diagrams module
• PyFlow
• Mermaid
• Plotly

Key principles for effective diagrams:

• Keep it simple and clean
• Use common formats (linear, divergent, radial)
• Don’t overcrowd with too many elements
• Leverage white space effectively
• Maintain consistent themes and organization

The C4 model by Simon Brown provides a structured approach to visualizing software architecture:

• Starts with system level
• Can be implemented through tools like IcePanel
• Generates diagrams from code

Best practices for diagram creation:

• Make it clear, concise, and purposeful
• Use color to differentiate values and components
• Follow left-to-right or top-down organization
• Avoid unnecessary complexity
• Consider your audience’s needs

Diagrams can be created through:

• Auto-generation from code
• Manual creation with editing tools
• Combination of both approaches

Good diagrams naturally lead to better documentation and clearer communication across teams
