Identification of particular genome regions through heat map representation. A: Circular representation of 12 Vibrionaceae genomes obtained using SynTView, showing their gene similarity relationships (heat map) and highlighting a particularly sparse region (bottom right). B: Figure taken from reference  representing the same genomes and describing the specific region highlighted as the superintegron of Vibrio cholerae.
