Task 3: Practice Data Analysis Using Jupyter Notebook

Description : 

1. Open Jupyter Notebook in your system.
2. Download or use any sample dataset (e.g., CSV file – student data, sales data, etc.).
3. Perform the following steps inside the notebook:

• Load the dataset using Pandas.
• Show the first 5 rows using .head().
• Check basic info and stats using .info() and .describe().
• Find missing values and handle them (drop or fill).
• Sort or filter data (e.g., students with marks > 80).
• Create at least 2 simple charts using Matplotlib or Seaborn (e.g., bar chart, pie chart).
