Visualization

Tree Interval provides multiple visualization options:

Basic ASCII Tree

Simple tree visualization with ANSI colors:

tree.visualize()

Output:

┌── Position(0, 100) type=Module
├── Position(10, 40) type=FunctionDef name=hello
└── Position(50, 90) type=ClassDef name=Example

Rich Pretty Printing

Enhanced visualization using the Rich library:

from tree_interval.rich_printer import RichTreePrinter, RichPrintConfig

# Custom configuration
config = RichPrintConfig(
    show_info=True,
    show_size=True,
    show_position=True,
    indent_size=2
)

# Print tree
printer = RichTreePrinter(config)
printer.print_tree(tree)

Custom Root Visualization

Visualize tree from any node:

# Using TreeVisualizer
tree.visualize(root=some_leaf)

# Using RichTreePrinter
printer = RichTreePrinter()
printer.print_tree(tree, root=some_leaf)

This allows viewing subtrees starting from any node in the tree structure.
