Google maps api 3 Google Maps API和GeoJSON：如何创建具有独特属性和信息窗口的不同颜色线条

我对GeoJSON和谷歌地图API有问题
如何使用…绘制多行线
1） 每一行都有自己的颜色和
2） 每行都有自己的属性和
3） 每一行都应该可以单击，并显示一个包含其属性的信息窗口

示例Javascript:

var-dataGEOJSON=[]；
函数LoadMyGEOJSON（键）
{
dataGEOJSON[key]=新的google.maps.Data（）；
dataGEOJSON[key].loadGeoJson（'GetLatLngGEOJSON.aspx？key='+key）；
dataGEOJSON[key].setMap（map）；
}

之所以使用该数组，是因为我可以跟踪他们加载的密钥，因为用户可以在其用户界面中从地图加载或卸载密钥。

示例GeoJSON：

{
“类型”：“FeatureCollection”，
“特点”：[
{
“类型”：“功能”，
“财产”：{
“钥匙”：“007”，
“第1行”：“，
“第2行”：“，
“第3行”：“，
“第4行”：“，
“第5行”：“，
“第6行”：“，
“第7行”：”
},
“几何学”：{
“类型”：“多重约束”，
“坐标”：[
