[运行示例](https://g2.antv.antgroup.com/zh/examples/general/line/line-sample/)

[资料索引](/llms.txt)

页面需要一个 `id="container"` 的 DOM 元素。以下为原始示例源码。

## 源码

```ts
/**
 * A recreation of this demo: https://observablehq.com/@d3/line-chart
 */
import { Chart } from '@antv/g2';

const chart = new Chart({
  container: 'container',
  autoFit: true,
});

chart.options({
  type: 'line',
  data: {
    type: 'fetch',
    value:
      'https://gw.alipayobjects.com/os/bmw-prod/551d80c6-a6be-4f3c-a82a-abd739e12977.csv',
  },
  encode: { x: 'date', y: 'close' },
  transform: [
    {
      type: 'sample',
      thresholds: 200,
      strategy: 'max',
    },
  ],
});

chart.render();
```
