# [SCH-30] Decision Tree · 의사결정 트리

> AI 붙여넣기 카드. 갤러리 런타임(`main.js`)이 아니라 이 파일을 가져와라.

## 언제 가져가나
루트 질문 → Yes/No 분기 → 잎 결론 — 의사결정/분류 규칙의 표준 트리.

**응용** 정책 분기, 트러블슈팅 체크리스트, 자격 판정, 분류 모델 설명.

## 데이터 모양
- family: `tree`
- dataShape: 6-cell diagram with 분기 트리 axis
- tasks: structure ideas, explain process, choose communication frame
- tags: tree, 분기 트리, 6cells, DecisionTree, 분류, 정책, 체크리스트

- schema.type: `tree`
- schema.cells: `6`
- schema.axis: `분기 트리`


## 의존
svg · load `low` · library `SVG`

## 붙여넣는 법
1. 라이브러리 없음. svg viewBox 0 0 400 240
2. 아래 body 를 svg 안에 넣는다
3. 색 변수(`${gold}` 등)는 T 토큰으로 치환한다

```js
const T = {
  "bg": "transparent",
  "fg": "#ece8f5",
  "sub": "#a59bbd",
  "grid": "rgba(255,255,255,.08)",
  "gold": "#e8c069",
  "royal": "#6b8cff",
  "rose": "#e07a9f",
  "teal": "#6dd2c4",
  "plum": "#b487e8"
};
const gold = T.gold, royal = T.royal, rose = T.rose, teal = T.teal, plum = T.plum, fg = T.fg, sub = T.sub;
const stroke = 'rgba(255,255,255,.18)';
const fill1 = 'rgba(232,192,105,.10)';
const fill2 = 'rgba(107,140,255,.10)';
const host = document.querySelector('#chart');
const body = `
