Google Maps Marker Clustering. Clustering or mapping can help you become aware of different ways to think about a subject. Plot a matrix dataset as a hierarchically-clustered heatmap.

However youll see in the next section an alternative method that keeps that data visible within the clusters. It is similar to the stats command but provides options for zoom levels and cells for mapping. If youre looking to measure density a heat map is also very effective and can incorporate your own numeric values.

This example uses Mapbox GL JS built-in cluster functions to visualize points in a circle layer as clusters. Rectangular data for clustering. Hierarchical cluster analyses of the rows.
