# [DIS-14] Variwide · 가변폭 막대

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

## 언제 가져가나
막대 높이 = 값, 막대 폭 = 가중치(표본 수) — 두 지표를 한 면적으로.

**응용** 부서별 평균×인원, 국가별 GDP×인구.

## 데이터 모양
- family: `composition`
- dataShape: category shares or weighted blocks
- tasks: show composition, show frequency, compare magnitudes, show part-to-whole
- tags: distribution, 비율, 빈도, composition, share, variwide, 가변폭, 막대


## 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);
  charts.push(c);
  return c;
