如何在BingMap上绘制基于图钉的多边形？

// 引入BingMap的JavaScript库
<script src="https://www.bing.com/api/maps/mapcontrol?key=YOUR_API_KEY"></script>

// 创建地图容器
<div id="map" style="width: 800px; height: 600px;"></div>

// JavaScript代码
<script>
    // 创建地图对象
    var map = new Microsoft.Maps.Map('#map', {
        credentials: 'YOUR_API_KEY'
    });

    // 创建图钉对象
    var pinLocation = new Microsoft.Maps.Location(47.6062, -122.3321);
    var pin = new Microsoft.Maps.Pushpin(pinLocation, {
        color: 'red'
    });

    // 将图钉添加到地图上
    map.entities.push(pin);

    // 创建多边形的坐标数组
    var polygonLocations = [
        new Microsoft.Maps.Location(47.6062, -122.3321),
        new Microsoft.Maps.Location(47.6097, -122.3331),
        new Microsoft.Maps.Location(47.6097, -122.3351),
        new Microsoft.Maps.Location(47.6062, -122.3351)
    ];

    // 创建多边形对象
    var polygon = new Microsoft.Maps.Polygon(polygonLocations, {
        fillColor: 'rgba(0, 0, 255, 0.5)',
        strokeColor: 'blue'
    });

    // 将多边形添加到地图上
    map.entities.push(polygon);
</script>
