[中文 README](./README.zh-CN.md)

F2 is **born for mobile**, developed for developers as well as designers. It is Html5 Canvas-based, and is also compatible with Node.js, Weex and React Native. Based on [the grammar of graphics](https://www.cs.uic.edu/~wilkinson/TheGrammarOfGraphics/GOG.html), F2 provides all the chart types you'll need. Our mobile design guidelines enable better user experience in mobile visualzation projects.

> Special thanks to [Leland Wilkinson](https://en.wikipedia.org/wiki/Leland_Wilkinson), the author of [*The Grammar Of Graphics*](https://www.cs.uic.edu/~wilkinson/TheGrammarOfGraphics/GOG.html), whose book served as the foundation for F2 and G2.

## Installation

```bash
$ npm install @antv/f2
```

## Features

### Born for mobile
- **Design for mobile**: make data more alive and chart interactions more natural.

- **Performance**: small package size(version without interaction is 44k after gzip) with great rendering performance.

- **Compatibility**: multi-end, Multi-runtime support. Besides H5 env, F2 can also run in [Node.js](https://antv.gitbook.io/f2/platform), [Weex rendering](https://github.com/weex-plugins/weex-chart) and [React Native](https://github.com/chenshuai2144/f2-demo), also [支付宝小程序](https://github.com/antvis/my-f2) and [微信小程序](https://github.com/antvis/wx-f2).

### All the chart types you want
With the power of grammar of graphics, F2 supports data-driven [50+ chart types](https://f2.antv.vision/zh/examples)(the amount can be even more, which is depended on you) including classical charts such as line, column/bar chart, pie chart, scatter plot, gauges, etc. Additionally, F2 also provides feature-riched chart components, such as Tooltip, Legend and Guide.

### Flexible and Interactive
We also provide developers with flexible extension mechanisms, including shape, animation, and interactive customization capabilities, as well as flexible styling to meet a variety of personalized charting requirements.
