import matplotlib.pyplot as plt

# Creating a DataFrame
data = {
    'Name': ['Alice', 'Bob', 'Charlie', 'Diana'],

    'Salary': [50000, 60000, 70000, 55000]
}

df = pd.DataFrame(data)

# Display basic information
print("DataFrame:")
print(df)
print("\nDataFrame Info:")
print(df.info())
print("\nStatistical Summary:")
print(df.describe())

# Data visualization
plt.figure(figsize=(10, 6))
plt.bar(df['Name'], df['Salary'])
plt.title('Employee Salaries')
plt.xlabel('Employee Name')
plt.ylabel('Salary')
plt.show()
