  2. Large dendrograms suffer occlusion problems • Occlusion • too nodes are fitted too closely or on top of others • hard to navigate and interact with the hierarchy • hard to identify patterns occlusion occlusion occlusion

  3. Concise overview + detail view A newmetricfor constructing a concise overview • Overview displays the • backbones of the hierarchy • Benefit • no occlusion • easy navigation & interaction • enhanced scalability A linked detail view displays selected sub-trees
