Quick answers
When should I pick Network graph maps?
When the story is: org influence maps, dependency graphs, classroom social maps.
When should I avoid Network graph maps?
Skip it in cases like: a simple org chart or bullet list already carries the claim.
Who invented or popularised it?
Force-directed layouts; Cytoscape.js and friends on GitHub
What does it encode?
nodes and edges with force or hierarchical layout
Is it OK in ads?
Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure.

Network graph maps encodes values as nodes and edges with force or hierarchical layout. Force-directed layouts; Cytoscape.js and friends on GitHub.
In reports, ads and assignments it fits org influence maps, dependency graphs, classroom social maps. Skip it when a simple org chart or bullet list already carries the claim.
Mistakes
- Failure modes 1 — a simple org chart or bullet list already carries the claim
- Failure modes 2 — 3-D pies and perspective bars
- Failure modes 3 — Dual axes that fake a correlation
- Failure modes 4 — Truncated axes that shout a small delta
- Failure modes 5 — Legend only, no direct labels
- Failure modes 6 — Missing source, unit or period
Fixes
- Fixes 1 — Return to org influence maps, dependency graphs, classroom social maps.
- Fixes 2 — Flat, one axis, direct labels.
- Fixes 3 — Color-blind-safe palette plus pattern.
- Fixes 4 — Rewrite the title as a claim and add a source line.
Network graph maps: honour nodes and edges with force or hierarchical layout, and switch when a simple org chart or bullet list already carries the claim.
