Binary Search Tree Visualizer

A Rust crate that provides visualization tools for binary search trees, including both ASCII art and SVG generation. This crate is great for educational purposes and debugging binary search tree implementations.

Features

ASCII art visualization of binary search trees
SVG generation for high-quality tree visualization
Simple and intuitive API
Customizable visualization parameters
Support for any type that implements Ord and Display traits

Installation

Add this to your Cargo.toml:

[dependencies]
binary-search-tree-visualizer = "0.1.0"

Or use:

cargo add binary-search-tree-visualizer

Usage

Here's a simple example of how to use the crate:

use binary_search_tree_visualizer::{BinarySearchTree, AsciiVisualizer, SvgVisualizer};
use binary_search_tree_visualizer::visualizer::TreeVisualizer;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create a binary search tree
    let mut tree = BinarySearchTree::new();

    // Insert some values
    tree.insert(5);
    tree.insert(3);
    tree.insert(7);
    tree.insert(1);
    tree.insert(9);

    // Generate ASCII visualization
    let ascii_viz = AsciiVisualizer;
    let ascii_output = ascii_viz.visualize(&tree)?;
    println!("{}", ascii_output);

    // Generate SVG visualization
    let svg_viz = SvgVisualizer::default();
    let svg_output = svg_viz.visualize(&tree)?;

    // Save SVG to file
    std::fs::write("tree.svg", svg_output)?;

    Ok(())
}

Visualization Examples

ASCII Art Output

└── 5
    ┌── 7
    │   ┌── 9
    └── 3
        └── 1

SVG Output

The SVG visualization will be saved to a file and can be viewed in any web browser or SVG-compatible viewer.

Customization

The SvgVisualizer can be customized with different parameters:

let svg_viz = SvgVisualizer {
    node_radius: 25.0,    // Size of node circles
    level_height: 80.0,   // Vertical spacing between levels
    horizontal_spacing: 50.0, // Horizontal spacing between nodes
};
