1. A visualization method for visualizing affinities between a plurality of objects, the method comprising the steps of: forming a representation of a minimum spanning tree wherein said minimum spanning tree connects said plurality of objects based on a pairwise distance between said plurality of objects; forming a hierarchical cluster of said plurality of objects wherein said hierarchical cluster comprises a level; agglomerating said plurality of objects based on said pairwise distance; displaying a view of said representation of said minimum spanning tree in a graphical user interface; receiving a user selection of a parameter containing a hierarchical level; and identifying, in said view, a target cluster that corresponds to said hierarchical level; wherein at least one of the steps is carried out using a computer device so that affinities between said plurality of objects are visualized.
