G2 is a visualization grammar, a data-driven visual language with a high level of usability and scalability. It provides a set of grammars, takes users beyond a limited set of charts to an almost unlimited world of graphical forms. With G2, you can describe the visual appearance and interactive behavior of a visualization just by one statement, and generate web-based views using Canvas or SVG.

## 📦 Installation

```bash

```

## 🔨 Getting Started

<img src="https://gw.alipayobjects.com/mdn/rms_2274c3/afts/img/A*8qbLQb7A0loAAAAAAAAAAABkARQnAQ" style="width: 600px">

Before drawing we need to prepare a DOM container for G2:

```html
<div id="c1"></div>
```

```ts
import { Chart } from '@antv/g2';

const data = [
  { genre: 'Sports', sold: 275 },
  { genre: 'Strategy', sold: 115 },
  { genre: 'Action', sold: 120 },
  { genre: 'Shooter', sold: 350 },
  { genre: 'Other', sold: 150 },
];

// Step 1: Create a Chart instance.
const chart = new Chart({
  container: 'c1', // Specify chart container ID
  width: 600, // Specify chart width
  height: 300, // Specify chart height
});

// Step 2: Load the data.
chart.data(data);

// Step 3: Declare the grammar of graphics, draw column chart.
chart.interval().position('genre*sold');

// Step 4: Render chart.
chart.render();
```
