ggtree

ggtree is an R package designed for the visualization and annotation of phylogenetic trees and other tree-like structures. It extends the ggplot2 plotting system, allowing users to leverage the grammar of graphics to map annotation data onto tree structures.

Key features include:

• Visualization of phylogenetic trees.
• Integration and annotation of associated data (covariates) onto tree structures.
• Compatibility with the ggplot2 ecosystem.
