The array produced gives the clusters each data point belongs to after running the hierarchical clustering algorithm. In this case we are using 3 clusters since we are working with 3 flower species. We are also using the ward linkage method.

Agglomerative hierarchical clustering illustration. Generally, Agglomerative Clustering can be divided into a graph and geometric methods (Figure 2). Graph methods use subgraph/interconnected points to represent the hierarchy (Figure 3) while geometric methods use a cluster center point and dissimilarity as the basis (Figure 4).
