DAG Visual Editor Design

Design modern, intuitive DAG and workflow visual editors. This skill captures best practices from industry leaders like n8n, ComfyUI, Retool Workflows, and React Flow — prioritizing clarity over complexity.

Philosophy: LEGO, Not LabView

Traditional node editors (LabView, Max/MSP, older VFX tools) suffer from:

• Dense, cluttered interfaces
• Overwhelming port/connection complexity
• Steep learning curves
• "Spaghetti" wire syndrome

Modern DAG editors take a different approach:

• LEGO-like composability — snap blocks together
• Progressive disclosure — show complexity only when needed
• Clear data flow — left-to-right or top-to-bottom
• Minimal chrome — the content IS the interface
