Visualizing Biodiversity with Voronoi Treemaps

Michael S. Horn, Matthew Tobiasz, Chia Shen
2009 2009 Sixth International Symposium on Voronoi Diagrams  
Introduced in 2005, the Voronoi treemap algorithm is an information visualization technique for displaying hierarchical data.  ...  In this paper, we present a multi-touch tabletop application called Involv that uses the Voronoi treemap algorithm to create an interactive visualization for the Encyclopedia of Life.  ...  ACKNOWLEDGMENTS We thank James Hanken from the Department of Organismic Evolutionary Biology at Harvard for his early discussions on the importance of visualizing phylogeny together with our initial taxonomy  ...

An Approach to Generate Spatial Voronoi Treemaps for Points, Lines, and Polygons

Song Tian, Ximin Cui, Yu Gong
2015 Journal of Electrical and Computer Engineering  
As a space-filling method, Voronoi Treemaps are used for showcasing hierarchies. Previously presented algorithms are limited to visualize nonspatial data.  ...  The approach of spatial Voronoi Treemaps is proposed in this paper to eliminate these problems by enabling the subdivisions for points, lines, and polygons with spatial coordinates and references.  ...  Subsequently, approaches to visualize the hierarchies with the nonrectangular regions were addressed, such as Voronoi Treemaps [11, 12] , Jigsaw Treemaps [13] , and Circular Treemaps [14] .  ...

DevoWorm: data-theoretical synthesis of C. elegans development [article]

Bradly John Alicea, Richard Gordon, Thomas E. Portegys
2018 bioRxiv   pre-print
Compared with the great diversity and plasticity found across the tree of life, Caenorhabditis elegans development is a rather unique model system.  ...  C. elegans biology provides us with a highly-deterministic developmental cell lineage, and a clear linkage from zygote to cells of the adult phenotype.  ...  Voronoi treemaps and Voronoi diagrams more generally have been applied to the study of embryogenesis [18] and biodiversity [19] .  ...
