Description

• 

Newick is a simple text-based format for describing a tree with edge lengths using parentheses and commas.

• 

The GraphTheory[Newick] can convert a Graph representing a tree to its Newick encoding as a string, and vice versa.

• 

The GraphTheory[ImportGraph] and GraphTheory[ExportGraph] commands can read from and write to this format.

• 

The general-purpose commands Import and Export also support this format.

Examples
