     Gaussian Naive Bayes Example using sklearn function.
     Iris type dataset is used to demonstrate algorithm.

+    Algorithm:
+    1. Load Dataset: Import the Iris dataset.
+    2. Data Preprocessing: Split dataset into features (X) and labels (y).
+    3. Model Initialization: Initialize Gaussian Naive Bayes model.
+    4. Model Training: Fit model using training data.
+    5. Make Predictions: Predict labels for the test dataset.
+    6. Evaluate Model: Calculate and display accuracy.
+    7. Visualize Results: Generate and display a normalized confusion matrix.
