Using Diagrams to Communicate Complex Ideas with Python
summary
Claim: diagrams produced from code become documentation and clarify architecture, not decoration. Examples show grouping EC2 instances routed to RDS with the diagrams Python library (pip install diagrams), a Sankey energy flow built with plotly Sankey, and textual diagrams rendered then polished via mermaid + draw.io. The C4 model generates container→component→code views, pyflow visualizes code as nodes, and outputs are layouted automatically so arrows, spacing and color convey hierarchy, contrast and surprising simplicity rather than hand‑drawn clutter.
