Angularjs geojson的有角小叶标记聚类

我想在地图上显示传单MarkerCluster，问题在于从GeoJSON检索数据：

{
    "type": "FeatureCollection",
    "features": 
    [
        {
            "type": "Feature",
            "id": "sto",
            "properties": {
                "name": "Stoke"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                   -0.0731,
                   51.5615
                ]
            }
        },
        {
            "type": "Feature",
            "id": "dal",
            "properties": {
                "name": "Dalston"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    -0.070,
                    51.545
                ]
            }
        },
        {
            "type": "Feature",
            "id": "wan",
            "properties": {
                "name": "Wandsworth"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    -0.1924,
                    51.4644
                ]
            }
        },
        {
            "type": "Feature",
            "id": "batt",
            "properties": {
                "name": "Battersea"
            },
            "geometry": {
                "type": "Point",
                "coordinates": [
                    -0.1677,
                    51.4638
                ]
            }
        }
    ]
}

我试图在两个例子中再现同样的情况：

有人知道为什么第二个示例中的MarkerCluster没有显示吗？

---

我是否遗漏了geojson中的某些属性？

您可以尝试以下内容（讨论和代码片段）

他们在我这边都展示了同样的东西不幸的是，在开始的时候，他们在我这边展示了同样的东西不幸的是，在开始的时候，情况并非如此

// Get the countries geojson data from a JSON
$http.get("test.geojson").success(function(data, status) {
    addGeoJsonLayerWithClustering(data);

    function addGeoJsonLayerWithClustering(data) {
        var markers = L.markerClusterGroup();
        var geoJsonLayer = L.geoJson(data, {
            onEachFeature: function (feature, layer) {
                layer.bindPopup(feature.properties.Nome.value);
            }
        });
        markers.addLayer(geoJsonLayer);
        leafletData.getMap().then(function(map) {
            map.addLayer(markers);
            map.fitBounds(markers.getBounds());
        });
    }

});
