I'm trying to arrange species into a sunburst (multilevel pie or ring) chart that summarizes their numbers at genus, family level and so on. I cannot seem to realize that with gnumeric (and neither with LibreOffice calc for that matter) as I happen to have too many "dimensions".
Here is an example of the gnumeric manual that shows how to use a sunburst chart:

My data however comes in such format that I don't have the same entry across all rings:
Kingdom Phylum Class Species_count
Animalia Arthropoda Insecta 2
Animalia Arthropoda Malacostraca 13
Animalia Bryozoa Gymnolaemata 59
Bacteria Cyanobacteria Cyanophyceae 8
Is it possible to realize that within gnumeric or LibreOffice?
