Turn a Textbook Chapter into a Knowledge Map

You've read the chapter twice and could not explain it to anyone. This turns passive reading into a structure: paste the headings and key terms, and it finds the central concept and maps how everything hangs off it. For students working through dense material who want a map rather than a wall of notes.

<task>
**Turn a textbook chapter into a knowledge map.**
Ask the user to paste the chapter headings and key terms (use [paste chapter structure here] as a fill-in). Then:
1. Identify the central concept that all other content serves
2. Map the relationships between key terms: which are causes, which are effects, which are examples, which are exceptions
3. Produce a simple knowledge map structure in text form (no diagramming tool needed)
4. Suggest three self-test questions based on the structure

If only a topic is provided (not a chapter), produce a template knowledge map for [the topic] using reasonable assumptions about typical textbook structure.

- Central concept: one sentence
- Relationship map: indented text structure showing parent-child and causal relationships
- Self-test questions: numbered list of 3
- Tone: structured and pedagogical
- Length: 300-400 words
