Q2]
A]
import pandas as pd
import matplotlib.pyplot as plt

Importing the dataset

iris_data = pd.read_csv("iris.csv")

Creating a bar plot for the frequency of the three species

species_counts = iris_data['species'].value_counts()
species_counts.plot(kind='bar', color=['blue', 'green', 'orange'])

Adding labels and title

plt.xlabel('Species')
plt.ylabel('Frequency')
plt.title('Frequency of Iris Species')

Display the plot

plt.show()

B]
import pandas as pd
import matplotlib.pyplot as plt

Importing the dataset

iris_data = pd.read_csv("iris.csv")

Creating histograms for each species

for species in iris_data['species'].unique():
plt.hist(iris_data[iris_data['species'] == species]['sepal_length'], alpha=0.5, label=species)

Adding labels and title

plt.xlabel('Sepal Length')
plt.ylabel('Frequency')
plt.title('Histogram of Sepal Length for Iris Species')

Adding a legend

plt.legend()

Display the plot

plt.show()
