Understanding Branching vs. Merging in Data Flow Diagrams #3698617 (License: Personal Use)

In diagram (a), a single blue source node branches into two identical blue destination nodes, illustrating a one-to-many distribution pattern. In diagram (b), two source nodes-one blue and one cyan-feed into a shared process, yielding three heterogeneous output nodes (blue, teal, cyan), demonstrating input combination and transformation. The arrows indicate directed flow, and color changes signify state or type evolution.

This image is commonly used in computer science education, data engineering documentation, or system architecture guides to explain fundamental data flow concepts like fan-out, fan-in, and transformation logic. It supports user intent to visualize how systems handle input/output relationships in pipelines or workflows.
