Generate a random array of 50 integers

np.random.seed(42)
data = np.random.randint(1, 100, 50)

Display using line chart, scatter plot, histogram, and box plot

fig, axes = plt.subplots(2, 2, figsize=(12, 8))

Line chart

axes[0, 0].plot(data, color='green')
axes[0, 0].set_title('Line Chart')

Scatter plot

axes[0, 1].scatter(range(1, 51), data, color='red')
axes[0, 1].set_title('Scatter Plot')

Histogram

axes[1, 0].hist(data, bins=10, color='blue', alpha=0.7)
axes[1, 0].set_title('Histogram')

Box plot

axes[1, 1].boxplot(data, vert=False)
axes[1, 1].set_title('Box Plot')

plt.tight_layout()
plt.show()

B]
import matplotlib.pyplot as plt

Create two lists representing subject names and marks obtained

subjects = ['Math', 'English', 'Science', 'History', 'Art']
marks = [90, 85, 92, 88, 78]

Display data in a pie chart

plt.pie(marks, labels=subjects, autopct='%1.1f%%', startangle=140, colors=['skyblue', 'lightcoral', 'lightgreen', 'lightpink', 'lightyellow'])
plt.title('Marks in Subjects')
plt.axis('equal') # Equal aspect ratio ensures that pie is drawn as a circle.

Display the plot

plt.show()
