# [INT-15] Drilldown Treemap · 드릴다운 트리맵

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

## 언제 가져가나
사각형을 클릭해 한 단계씩 줌인하고 breadcrumb로 복귀 — 계층형 비중 분석의 실무형 인터랙션.

**응용** 카테고리→브랜드→상품 매출, 폴더 용량, 조직별 예산 구조.

## 데이터 모양
- family: `hierarchy`
- dataShape: click-to-drill treemap
- tasks: explore data, monitor change, drill into structure, show hierarchy, drill into nested blocks
- tags: interactive, live, exploration, hierarchy, tree, treemap, drilldown, 드릴다운, 트리맵


## 의존
echarts@5 · load `low` · library `ECharts`

## 붙여넣는 법
1. echarts 5.x 로드 (GL이면 echarts-gl도)
2. 컨테이너 id를 원본 id와 맞추거나 `document.getElementById` 한 줄만 바꾼다
3. `T`, `reg`, `cssv` 가 필요하면 갤러리 테마 스텁을 함께 가져간다

```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 cssv = (n, fb) => (getComputedStyle(document.documentElement).getPropertyValue(n).trim() || fb);
const isDark = () => document.documentElement.getAttribute('data-theme') !== 'light';
const charts = [];
const reg = (id, opt) => {
  const dom = document.getElementById(id); if (!dom) return;
  const c = echarts.init(dom, null, {renderer:'canvas'});
  c.setOption(opt);
