    Why Visual Diagrammatic Languages Fit the AI-Driven Vibe-Coding Workflow

    The reliance on sequential ASCII text is a historical constraint of 1950s hardware. As AI code generators shift developer tasks from writing syntax to reviewing structures, relational dataflow diagrams compile directly to native code, eliminating parsing overhead and merge conflicts.
