However, you could create a "clustergram":
@article{schonlau:2002,
Author = {Schonlau, Matthias},
Journal = {The Stata Journal},
Pages = {316-327},
Title = {The clustergram: A graph for visualizing hierarchical and
non-hierarchical cluster analyses},
Volume = {3},
Year = {2002},
Url = {http://www.schonlau.net/clustergram.html}
}
