Concept map as an outline and diagram code

Map how the ideas in a topic connect, as a text outline plus Mermaid code you can paste into a diagram tool.

Change note: Initial version

Prompt

Build a concept map of {{topic}} for a {{level}} learner.

Deliver:
1. **Central idea** and 5 to 8 main concepts around it, each with a one-line definition.
2. **Relationships**: a list of links written as "Concept A -> relation -> Concept B" (for example "supply -> sets price with -> demand"). Include at least 10 links and at least two cross-links between different branches.
3. **Mermaid diagram**: a valid `graph TD` block using those concepts and labeled edges. Keep node text short.
4. **Reading path**: the order I should learn the concepts, with a reason for each step.
5. **Gaps**: two related areas not covered by the map that I might explore next.

Focus on how things connect, not only on definitions. Be accurate and do not stretch the map to fill space. If you are unsure about a fact, say so plainly. Never invent citations, quotes, statistics or URLs.

  Default: High school

Example output

**Central idea:** Photosynthesis turns light, water and carbon dioxide into sugar and oxygen.

**Main concepts:** chloroplast (the organelle where it happens), chlorophyll (pigment that captures light), light reactions (make ATP and NADPH), Calvin cycle (builds sugar), stomata (gas entry), glucose (stored energy).

**Links**
- sunlight -> is absorbed by -> chlorophyll
- chlorophyll -> powers -> light reactions
- light reactions -> split -> water
- light reactions -> supply ATP and NADPH to -> Calvin cycle
- stomata -> admit -> carbon dioxide
- Calvin cycle -> uses carbon dioxide to make -> glucose
- (cross-link) glucose -> fuels -> cellular respiration

```mermaid
graph TD
  A[Sunlight] -->|absorbed by| B[Chlorophyll]
  B -->|drives| C[Light reactions]
  C -->|ATP and NADPH| D[Calvin cycle]
  E[Stomata] -->|admit CO2| D
  D -->|makes| F[Glucose]
```

**Reading path:** chloroplast, light, light reactions, Calvin cycle, then respiration.
**Gaps:** C4 and CAM photosynthesis; how plants regulate stomata.

Notes

The labeled links force relationships, which is what concept maps are for. Paste the Mermaid block into mermaid.live or a compatible note app.
