Treemap of the proportion of variant affect atributed to each kind of sequence alteration in Ensembl human GVF dataset (release 69). A treemap displays hierarchcal data as nested rectangles. In this dataset there are four kinds of sequence alteration annotated: insertion, deletion, substitution and SNV, each with a different color. For each sequence alteration, the annotated variant effects are shown with the size of the rectangle proportional to the number of occrurences of that annotation, and the count is provided where space permits. The treemap was generated using the IBM Manyeyes tool (http://www-958.ibm.com/)
