# 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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.xrdev.app/mixed-reality-docs/lessons/lesson-5/project/what-is-clustering-map-pins-means.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
