**Repository Path**: LLCPro/L7

## Basic Information

- **Project Name**: L7
- **Description**: L7 是由蚂蚁金服 AntV 数据可视化团队推出的基于 WebGL 的开源大规模地理空间数据可视分析开发框架。L7 中的 L 代表 Location，7 代表世界七大洲，寓意能为全球位置数据提供可视分析的能力。L7 以图形符号学为理论基础，将抽象复杂的空间数据转化成 2D、3D 符号，通过颜色、大小、体积、纹理等视觉变量实现丰富的可视化表达。

Large-scale WebGL-powered Geospatial data visualization analysis framework.

[中文 README](./README.zh-CN.md)

[GitHub](https://github.com/antvis/L7)

Powered by WebGL, the rendering technology of L7 supports fast and efficient rendering of big data, 2D/3D rendering, possible through calculation and analysis of spatial data by GPU Parallel Compu-ting.

L7 focuses on geographic data expressiveness，interaction and design of geographic visualization layers. The basemaps on the platform are powered by third-party services

## 🌟 Highlight features of L7 2.0

- 🌏 Data-driven Visualization

  Layer visualization API design base Semiology of Graphics.

  It supports rich map visualization types for a better insight on data.

- 🌏 High performance rendering with 2D/3D effect
  Real-time and dynamic rendering with millions of spatial data.

- 🌏 Simple and flexible data format

  L7 supports a wide variety of data formats including CSV, JSON, geojson, among others, eliminating the need to run conversions ahead of time.

- 🌏 Multi-basemap

  For global users, Mapbox is easy to be embedded by a simple line of code.

## Getting Started

### 📦 Installation

```
npm install @antv/l7@beta
```

### Init Map by L7 scene

```javascript
import { Scene } from '@antv/l7';
import { Mapbox } from '@antv/l7-maps';

const scene = new Scene({
  id: 'map',
  map: new Mapbox({
    style: 'light',
    pitch: 0,
    center: [107.054293, 35.246265],
    zoom: 4.056,
  }),
});
```

### Add Layer

```javascript
import { PointLayer } from '@antv/l7';

const pointLayer = new PointLayer()
  .source(data)
  .shape('circle')
  .size('mag', [1, 25])
  .color('mag', ['#5B8FF9', '#5CCEA1'])
  .style({
    opacity: 0.3,
    strokeWidth: 1,
  });

scene.addLayer(pointLayer);
```
