Binary Tree Diagram Visualization in Java

Printing a binary tree in a graphical format can provide a clear representation of its structure. In Java, achieving this involves traversing the tree and generating a diagram based on the nodes' relationships.

One solution involves using a tree printing library. For instance, the TreePrint library allows you to convert a binary tree into an easily-readable ASCII diagram.

Alternatively, you can write a custom implementation. To do so, define a Node class as provided in the question:

public class Node {
    Node left, right;
    A data;
    
    public Node(A data){
        this.data = data;
    }
}

Your task is then to traverse the tree and print it in a level-by-level format. This can be achieved using a breadth-first search algorithm, which involves visiting each level of the tree before proceeding to the next.

While the provided code in the question focuses on printing binary trees in a specific format, the general approach remains the same for printing trees of any structure. Libraries like TreePrint provide convenience and additional features for handling complex tree structures.
