Maximum sizes of Thunnus tuna species. (centimetres)

Other version

• 

  Only species in Thunnus genus.

Creation info

Created in Ruby using SVG::Graph v0.6.1 by Pengo. And then hand-massaged (to make the x-axis use black text, put species names in italics, and shift labels by a few pixels so that they line up properly).
