Figure 1. Evolutionary relationship of clade 23I with other clades in India.

The figure represents the phylogenetic relationship of clade 23I with other clades identified in Indian sequences during the study period. The horizontal axis of the phylogenetic tree denotes the number of mutations, with the numbers increasing progressively from left to right. The branches, represented by horizontal lines, signify evolutionary divergence over time. The length of the branch horizontally correlates with the amount of change. The vertical axis on the other hand organizes the clade labels in a spatial manner for clarity. It does not imply any phylogenetic or temporal relationship.
