Newick format

The Newick format is a way to represent tree structures, particularly phylogenetic trees, in a textual form. It uses a nested, parentheses-based notation that allows the representation of hierarchical relationships among various entities, such as species or genes, in a succinct manner. Each node in the tree can represent a taxon (e.g., a species) or a clade (a group of taxa), and the branches indicate evolutionary relationships.
