 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.

 ### Installation
 
 ```
 npm install @antv/l7@beta
 ```
 
+### init Map by L7  scene
+
+```javascript
+import { Scene } from '@antv/l7';
+import { Mapbox } from '@antv/l7-maps';
+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);
+
+```
