Problem 4: Check Class Balance with a Count Plot

Problem Description

Write a Python program that uses sns.countplot() to visualize the class distribution of a binary target column, to check for imbalance.

Input

A DataFrame with a binary "target" column.

Output

A displayed bar chart showing the count of each class.

Constraints

• At least 10 rows, with an imbalanced class distribution.

Example Input

text
{"target": [0,0,0,0,0,0,0,0,1,1]}

Example Output

text
(A bar chart showing 8 bars-worth of class 0 and 2 bars-worth of class 1, visually revealing the imbalance)

Concepts Covered

sns.countplot(), class balance visualization.
