A clustering algorithm which works by first creating a grid of clusters This clustering algorithm attempts to merge clusters so that cluster labels will not be incorrectly placed. This should mean that the center of any cluster icon will be over the centroid of the cluster.

Remarks
First partitions the features into a grid of small sub clusters Where possible these sub clusters are combined into a grid of clusters. Edge sub clusters are not initially placed on the grid - instead they are merged into adjacent clusters in a second pass. This is so that the cluster labels do not have to be drawn a large distance from the centroid of the cluster.
