A network diagram is a graph-drawing that represents entities as nodes and their relationships as edges (directed or undirected), enabling visualization of topology, centrality measures, clusters, and connectivity patterns in complex systems. Developed from graph theory in mathematics, it is used in project management (PERT/CPM), systems engineering, social network analysis, and computer network design. Persistence mechanism: created in diagramming software (draw.io, Visio, Graphviz), exported as image or vector formats, and stored in documentation systems.

Definition
Why it is in scope
A human-made visual representation showing the connections and relationships between discrete entities (nodes) through linking lines (edges), used in project management, systems engineering, sociology, and computer science to model structure, flow, and topology. Persisted through software tools, printed diagrams, and digital collaboration platforms.

A network diagram IS a specific kind of diagram — it represents entities as nodes and relationships as edges for visualization of topology and connectivity. A competent speaker would call a network diagram 'a diagram'. Law 9 INSTANCE_OF.
- cmsm0pxyb003n1q13a3ybbikcDERIVED_FROM →
Network diagrams DERIVED_FROM graph theory — they are visual applications of graph-theoretic concepts (nodes, edges, paths) to represent relationships. Graph theory existed first as the mathematical foundation, and network diagrams were later built from it.
