### Initialize and Render Score

Source: https://github.com/flufy3d/jianpurender/blob/main/README.md

Initialize the JianpuSVGRender with score data, configuration options, and a container element. This snippet demonstrates basic score rendering with notes, key signatures, and time signatures.

```typescript
import { JianpuSVGRender } from 'jianpurender';

// 初始化容器
const container = document.getElementById('score-container')! as HTMLDivElement;

// 创建渲染实例
const renderer = new JianpuSVGRender(
  {
    notes: [
      { start: 0, length: 1, pitch: 60 },
      { start: 1, length: 1, pitch: 62 },
      { start: 2, length: 1, pitch: 64 },
      { start: 3, length: 1, pitch: 65 },
      { start: 4, length: 1, pitch: 67 },
      { start: 5, length: 1, pitch: 69 },
      { start: 6, length: 1, pitch: 71 },
      { start: 7, length: 1, pitch: 72 }
    ],
    keySignatures: [{ start: 0, key: 0 }],
    timeSignatures: [{ start: 0, numerator: 4, denominator: 4 }]
  },
  { noteHeight: 24 },
  container
);
```
