From: Analysis of codon usage bias of mitochondrial genome in Bombyx moriand its relation to evolution
Correspondence analysis of the synonymous codon usage towards the codons in mtDNA. The analysis was based on the RSCU value of the 59 synonymous codons. The positions of each codon located in a super dimensional space were described in the first two-main-dimensional coordinates. Different base ended codons were marked in the figure, where the black point, white square, black triangle, white triangle refer to codons ending with A, T, C, G respectively.
