Mind map encodes values as radial branches around a central topic. Popularised by Tony Buzan from the 1970s; older radial notes exist.
In reports, ads and assignments it fits brainstorming, revision notes, early structure. Skip it when you must prove a claim with evidence in order.
Parts
- Mark — The core mark of Mind map is radial branches around a central topic.
- Scale — The scale must show zero (or a declared break) and units.
- Axis — Axis titles name the variable, not a mood.
- Legend — A legend is weaker than a direct label. Write beside the mark when you can.
- Label — Numbers are optional. If comparison is the job, label the ends only.
- Grid — Keep the grid faint. Data should own the ink.
- Annotation — One annotation sentence. Date the source.
- Frame — A thin frame. Never a 3-D box.
