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

```bash

npm install @antv/l7

```

### 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);

```
