One-sentence brief
A globe, map, timeline, network, document reader, or mixed view can each clarify one question and distort another. Selecting the mode from the evidence and task reduces spectacle, hidden uncertainty, and false causal inference.
WORLD EVENT LITERACY
A deterministic, local-only planner that recommends presentation families from the reader task, geographic shape, chronology, uncertainty, source density, motion preference, and bandwidth constraints.
ORIENTATION
A globe, map, timeline, network, document reader, or mixed view can each clarify one question and distort another. Selecting the mode from the evidence and task reduces spectacle, hidden uncertainty, and false causal inference.
LOCAL-ONLY PLANNING AID
The planner uses bounded choices and transparent repository-authored rules. It does not load a dataset, geolocate a person, contact an external service, or decide whether an event account is true.
WORKING BRIEF
Locating, tracing change, comparing states, inspecting documents, explaining relationships, quantifying trends, and teaching a sequence require different visual structures.
Geographic scale, temporal pattern, uncertainty, source density, and relationship structure determine which visual encodings are legible and honest.
Reduced motion, keyboard-only use, screen readers, magnification, mobile screens, and constrained bandwidth should affect the initial mode choice.
The planner recommends two presentation families and explains the rule trace. A supporting document or statistical view may be necessary even when the map or timeline is primary.
Cropping, sequencing, animation, projection, summarization, and uncertainty are editorial transformations. Their presence and limits must remain visible.
A polished map or animation cannot authenticate a source, establish a causal mechanism, fill an archival gap, or resolve a contested historical interpretation.
COMPLETE DOSSIER
Terms are defined for this site’s evidence method, not as universal legal or clinical definitions.
| Reader task | Likely primary family | Supporting family | Primary risk |
|---|---|---|---|
| Locate or compare geography | Static map or before-and-after | Document or statistical panel | Projection, scale, and cropped context |
| Trace sequence or change | Timeline or small multiples | Map or document reader | Omitted intervals and false causality |
| Explain relationships | Network graph | Timeline or map | Hairball clutter and inferred direction |
| Inspect source evidence | Document reader | Timeline or map | Source omission and decontextualized excerpts |
| Quantify change | Statistical panel | Map or document reader | Hidden denominators and uncertainty |
| Teach a guided sequence | Narrative sequence | Static overview and transcript | Scrolljacking, spectacle, and motion dependence |
Does the primary mode directly support the reader's main question?
Pass condition: The mode is selected from the task and evidence shape, not visual novelty.
Can every consequential mark, sequence, crop, and summary be traced to accessible source context?
Pass condition: Source links, dates, uncertainty, and transformations remain visible.
Can keyboard, reduced-motion, screen-reader, mobile, and low-bandwidth users reach the same conclusion?
Pass condition: A semantic transcript, structured table, and static alternative carry equivalent information.
Is there a defined condition for removing or simplifying a misleading visualization?
Pass condition: Confusion, source mismatch, geographic error, motion harm, or context loss triggers revision or rollback.
