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); ``` ## 🔗 Links - [L7Draw](https://github.com/antvis/L7Draw) - [L7Plot](https://github.com/antvis/L7Plot) - [LarkMap](https://github.com/antvis/LarkMap) - [LocationInsight](https://locationinsight.antv.antgroup.com) ## ✅ License [MIT license](./LICENSE).
