CGR and FCGR

Graphical representation of genomes
and oligonucleotide frequencies

Chaos Game Representation (CGR)
as described by Jeffrey (1990).
Represents DNA primary sequence organization.

Chaos Game Representation of Frequencies (FCGR)
as described by Deschavanne at al. (1999).
Represents frequencies of oligonucleotides.
