Designers use connecting lines, flowchart-style layouts, node-and-edge relationships, and annotated schematics to explain processes, product architectures, or organisational structures. SVG and canvas-based rendering allow these elements to be interactive and responsive.
Developer tools, SaaS platforms, API documentation, and infrastructure products frequently adopt this style because their offerings involve interconnected systems. The diagrammatic approach makes abstract technical concepts tangible and scannable.
