# Breast Cancer Prediction with Decision Tree Classifier

This Python script demonstrates the implementation of a Decision Tree Classifier for predicting breast cancer outcomes. 

**Key Features:**

* **Data Loading and Preprocessing:**

    - Loads breast cancer data from a CSV file.

    - Cleans the data by removing rows with missing values.

    - Preprocesses the data by:

        - Encoding categorical variables using LabelEncoder.

        - Scaling numerical features using StandardScaler.

* **Model Training and Evaluation:**

    - Splits the data into training and testing sets.

    - Performs hyperparameter tuning using Grid Search with Cross-Validation to find the best model configuration.

    - Trains the Decision Tree Classifier with the optimal hyperparameters.

    - Evaluates the model's performance using accuracy, classification report, and confusion matrix.

* **Visualization:**

    - Visualizes the trained decision tree using `plot_tree()` for better understanding of the model's decision-making process.

**Installation:**

1. Make sure you have the following libraries installed:

   - pandas

   - scikit-learn

   - matplotlib

   You can install them using pip:

   ```bash

   pip install pandas scikit-learn matplotlib
