This Voronoi Treemap encodes a KEGG related gene funcitonal classification scheme as colors and the cellular investment of HEK cells as area sizes. Abundance treemaps have been presented by our group at the VizBi2014 conference. A more complete data set is presented at www.proteomaps.net and was published in collaboration with Ron Milo and coworkers from the Weizmann Institute of Science in Israel 2014 in PNAS.

 

In meta-omics studies abundance treemaps can be used to visualize the compostion of complex communites. Here the abundance of different taxa embedded in the phylogenetic tree can be presented. This was exemplary shown in our review on data visualization in envrionmental proteomics 2013 in Proteomics.
