Data Flow Diagram (DFD) Symbols and Components - Visual Guide #56580 (License: Personal Use)

This image displays standard Data Flow Diagram (DFD) symbols: rectangular documents with folded corners, cylindrical data stores, trapezoidal external entities, and floppy disk-shaped terminators. Below are two histogram visualizations labeled “Histogram & Camera Information,” illustrating how sensor or imaging data might be represented in a system model. The color-coded and grayscale variants support accessibility and print-friendly documentation.

Used in software engineering, systems analysis, and business process modeling to illustrate how data moves through a system; commonly appears in technical documentation, UML/DFD tutorials, and system design presentations where users seek clarity on diagram notation.
