I have below code and output, I would like to learn how to make it animated.

def plot_class_distribution(data_path):
    class_counts = {}

    # Count the number of images in each class
    for directory in os.listdir(data_path):
        if os.path.isdir(os.path.join(data_path, directory)):
            class_counts[directory] = len(os.listdir(os.path.join(data_path, directory)))

    # Plot the class distribution as a pie chart
    plt.figure(figsize=(8, 6))  # Set the figure size here
    plt.pie(class_counts.values(), labels=class_counts.keys(), autopct='%1.1f%%', startangle=140,
           textprops={'fontsize': 8})
    plt.title('ASL Class Distribution')
    plt.axis('equal')  # Equal aspect ratio ensures that pie is drawn as a circle.
    plt.tight_layout()
    plt.show()
plot_class_distribution(data_path)

I have attempted with below code but it failed to output anything. Any smart pants please help chip in.

import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
import matplotlib.cm as cm
import os

def update(frame):
    ax.clear()
    ax.pie(frame, labels=class_counts.keys(), autopct='%1.1f%%', startangle=140, textprops={'fontsize': 8})
    ax.set_title('ASL Class Distribution')

def plot_class_distribution(data_path):
    global class_counts, ax
    
    class_counts = {}

    # Count the number of images in each class
    for directory in os.listdir(data_path):
        if os.path.isdir(os.path.join(data_path, directory)):
            class_counts[directory] = len(os.listdir(os.path.join(data_path, directory)))
    
    fig, ax = plt.subplots(figsize=(8, 6))
    ani = FuncAnimation(fig, update, frames=class_counts.values(), repeat=False)
    plt.show()
