 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

 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 专注数据可视化化表达，通过颜色、大小、纹理，方向，体积等视觉变量设置实现从数据到信息清晰，有效的表达。
 
 L7 能够满足常见的地图图表，BI 系统的可视化分析、以及 GIS，交通，电力，国土，农业，城市等领域的空间信息管理，分析等应用系统开发需求。
