+What are some other visualisation ideas to quickly debug a red black tree
+
+GitHub Copilot Chat:
+Here are some additional visualization ideas to quickly debug a red-black tree:
+
+1. **Graphical User Interface (GUI) with Swing**:
+   - Create a Swing application to draw the tree structure.
+   - Use different colors for red and black nodes.
+
+2. **Graphviz/DOT Language**:
+   - Generate a DOT file representing the tree.
+   - Use Graphviz to render the tree as an image.
+
+3. **ASCII Art**:
+   - Print the tree structure in the console using ASCII characters.
+   - Indicate node colors with text annotations.
+
+4. **Web-based Visualization**:
+   - Use a web framework (e.g., D3.js) to create an interactive tree visualization.
+   - Display the tree in a web browser with color-coded nodes.
+
+### Example: Graphviz/DOT Language
+
+#### Plan
+1. Create a method to generate a DOT representation of the tree.
+2. Use Graphviz to render the DOT file.
+
+#### Code
+
+```java
+package oplossing;
+
+import java.io.FileWriter;
+import java.io.IOException;
+
+public class RedBlackTree<E extends Comparable<E>> {
+    private ColoredNode<E> root;
+
+    public ColoredNode<E> root() {
+        return root;
+    }
+
+    public boolean add(E value) {
+        // Implementation of add method
+        return true;
+    }
+
+    public void generateDotFile(String filename) throws IOException {
+        try (FileWriter writer = new FileWriter(filename)) {
+            writer.write("digraph G {\n");
+            if (root != null) {
+                generateDotFile(root, writer);
+            }
+            writer.write("}\n");
+        }
+    }
+
+    private void generateDotFile(ColoredNode<E> node, FileWriter writer) throws IOException {
+        if (node.getLeft() != null) {
+            writer.write("  \"" + node.getValue() + "\" -> \"" + node.getLeft().getValue() + "\" [color=" + (node.getLeft().getColour() == 0 ? "black" : "red") + "];\n");
+            generateDotFile(node.getLeft(), writer);
+        }
+        if (node.getRight() != null) {
+            writer.write("  \"" + node.getValue() + "\" -> \"" + node.getRight().getValue() + "\" [color=" + (node.getRight().getColour() == 0 ? "black" : "red") + "];\n");
+            generateDotFile(node.getRight(), writer);
+        }
+    }
+}
+```
+
+### Example: ASCII Art
+
+#### Plan
+1. Create a method to print the tree structure using ASCII characters.
+2. Traverse the tree and format the output.
+
+#### Code
+
+```java
+package oplossing;
+
+import java.util.LinkedList;
+import java.util.Queue;
+
+public class RedBlackTree<E extends Comparable<E>> {
+    private ColoredNode<E> root;
+
+    public ColoredNode<E> root() {
+        return root;
+    }
+
+    public boolean add(E value) {
+        // Implementation of add method
+        return true;
+    }
+
+    public void printAsciiTree() {
+        if (root == null) {
+            System.out.println("Tree is empty.");
+            return;
+        }
+
+        Queue<ColoredNode<E>> queue = new LinkedList<>();
+        queue.add(root);
+
+        while (!queue.isEmpty()) {
+            int levelSize = queue.size();
+            while (levelSize > 0) {
+                ColoredNode<E> node = queue.poll();
+                if (node != null) {
+                    System.out.print(node.getValue() + "(" + (node.getColour() == 0 ? "B" : "R") + ") ");
+                    queue.add(node.getLeft());
+                    queue.add(node.getRight());
+                } else {
+                    System.out.print("null ");
+                }
+                levelSize--;
+            }
+            System.out.println();
+        }
+    }
+}
+```
