Answer 1

Have you looked at Weka's HierarchicalClusterer class?

In any case, the agglomerative hierarchical clustering algorithm is fairly straightforward, assuming you have a function that yields the distance value between two clusters.

For a standard example, Kruskal's minimum spanning tree algorithm proceeds by clustering nearby nodes.
