Data Flow Diagram - Layered Document Structure Visualization #221940 (License: Personal Use)

This stylized illustration shows a multi-layered 3D box representing a data or document processing pipeline, with annotated internal sections and directional arrows indicating flow. The sketch includes handwritten labels like “A1” and “B2”, suggesting modular components or versioned stages. Shading and perspective give depth, reinforcing the conceptual hierarchy and interconnectivity of system elements.

Used in technical documentation, software architecture presentations, or UX design guides to explain layered systems, data inheritance, or workflow stages; targets engineers, product managers, and designers seeking intuitive visual metaphors.
