||
[](https://travis-ci.com/antvis/L7) [](https://www.npmjs.com/package/@antv/l7) 
|
||
|
||
Large-scale WebGL-powered Geospatial data visualization analysis framework.
|
||
|
||
[中文 README](./README.zh-CN.md)
|
||
|
||
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.

||
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);
|
||
```
