You can also easily attach different components ( markers, information texts, controls, ground overlays, polygons, polylines) to the map.
您还可以轻松向地图添加几个不同的组件（标记、信息文本、控件、地表覆盖、多边形、多段线）。
Similarly, adding polylines ( lines with multiple vertices) requires storing some data.
同样地，添加polyline（具有多个顶点的线）需要存储一些数据。
Basic shapes: rectangles, circles, ellipses, lines, polylines, and polygons
基本形状：矩形、圆、椭圆、直线、折线以及多边形
Parallel coordinate technology is one of important tools to visualize multi-dimension data, but when polylines is crossing it is difficult to distinguish and the result is confused when the amount of data is larger.
其中平行坐标技术是信息可视化技术中处理多维数据的主要手段之一，传统的平行坐标技术存在着难以区分相交折线，数据量较大时可视化结果比较混乱等缺点。
