Constructing Overview + Detail Dendrogram-Matrix views Jin CHEN (presenter) Alan M. MacEachren Donna J. Peuquet GeoVISTA Center Department of Geography Penn State University InfoVis 2009 – Oct 14, Atlantic City, New Jersey
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
Concise overview + detail view A linked detail view displays selected sub-trees Overview displays the backbones of the hierarchy Benefit - no occlusion - easy navigation & interaction - enhanced scalability A new metric for constructing a concise overview
Time and Place for our presentation Wednesday, 10:50AM Session of Bioinformatics Visualization
