# How to cluster map pins for larger data-sets?

An advantage to using the **MapPinLayer** is that it **supports clustering**. If a **ClusterMapPin prefab** is specified on the layer, MapPins will be **clustered automatically.** When MapPins are clustered, the ClusterMapPin is shown in the place of the many MapPins that associate to it.

{% hint style="info" %}
**Clustering** is highly **recommended** for **large data sets** as this will reduce the number of MapPin instances that need to be rendered for zoomed out views.
{% endhint %}

Besides this rendering performance benefit, it is often preferable to cluster MapPins from a **usability** perspective since dense, cluttered views will make it more difficult for the user to interact with individual MapPins because the map pins might **overlap** with each other.

Clusters are **created at every zoom level**, so as the zoom level of the MapRenderer changes, the visible clusters and MapPins may change as well.
