Map with leaflet: two points on the map, in the same location - dictionary

Question

I have two points on the map, in the same location, but when I show on the map, one is superimposed on the other, not being able to see both at the same time.
How can I solve this problem?

You can use Marker Clustering plugin for Leaflet
var map = new L.Map("map",{preferCanvas:true}).setView([48.86, 2.35], 12),
tiles = L.tileLayer("http://{s}.tile.osm.org/{z}/{x}/{y}.png", {
attribution: '© OpenStreetMap contributors'
}).addTo(map),
markerClusterLayer = L.markerClusterGroup({
disableClusteringAtZoom: 13
,animate:false
}).addTo(map);
// Add vectors of the new type directly to MCG.
for (var i = 0; i < 30; i += 1) {
new L.marker(randomCoords()).addTo(markerClusterLayer);
}
function randomCoords() {
return [
48.86 + 0.1 * Math.random() - 0.05, 2.35 + 0.16 * Math.random() - 0.08
];
}
#map {
width: 800px;
height: 600px;
border: 1px solid #ccc;
}
#progress {
display: none;
position: absolute;
z-index: 1000;
left: 400px;
top: 300px;
width: 200px;
height: 20px;
margin-top: -20px;
margin-left: -100px;
background-color: #fff;
background-color: rgba(255, 255, 255, 0.7);
border-radius: 4px;
padding: 2px;
}
#progress-bar {
width: 0;
height: 100%;
background-color: #76A6FC;
border-radius: 4px;
}

<div id="map"></div>
<span>Mouse over a cluster to see the bounds of its children and click a cluster to zoom to those bounds</span>
Update
You can use Leaflet.FeatureGroup.SubGroup : It dynamically add/remove groups of markers from Marker Cluster.

Hope this will helps you.
