Why Combine Web Scraping and Data Visualization?

Web scraping lets you collect fresh, real-world data from the internet. Data visualization helps you turn that raw data into clear, actionable insights.
By combining both, you create a powerful workflow:
- Extract information from any website
- Clean and organize it
- Visualize trends, patterns, and outliers

Analogy:
Think of web scraping as gathering ingredients from the market, and data visualization as cooking a delicious meal. One without the other is incomplete!

Project Overview: What Will You Build?

In this beginner project, you’ll: - Scrape product prices and ratings from a sample e-commerce site - Clean and organize the data using Python - Create a bar chart showing product prices

You’ll use:
- requests and BeautifulSoup for scraping
- pandas for data cleaning
- matplotlib for visualization

Getting Started: Prerequisites

• Python basics: Variables, loops, functions (Cinute Digital’s Python for Beginners)
• Libraries: Install with pip: bash pip install requests beautifulsoup4 pandas matplotlib
• A code editor: VS Code, PyCharm, or Jupyter Notebook

Step 1: Scrape Data from the Web

Here’s a simple script to extract product names and prices:

import requests
from bs4 import BeautifulSoup

url = "https://example.com/products"
response = requests.get(url)
soup = BeautifulSoup(response.text, "html.parser")
products = soup.find_all("div", class_="product")

data = []
for product in products:
    name = product.find("h2").text
    price = product.find("span", class_="price").text.replace('₹', '').replace(',', '')
    rating = product.find("span", class_="rating").text
    data.append([name, float(price), float(rating)])

Tip:
For dynamic (JavaScript) sites, use selenium. For large projects, see Python Web Scraping for Beginners: Build Real-World Projects.

Step 2: Clean and Prepare Your Data

Now, let’s organize the scraped data using pandas:

import pandas as pd

df = pd.DataFrame(data, columns=['Product Name', 'Price', 'Rating'])
df['Price'] = df['Price'].astype(float)
df['Rating'] = df['Rating'].astype(float)
# Remove outliers or missing values if needed
df = df.dropna()
print(df.head())

Step 3: Visualize Your Data with Python

Let’s plot a bar chart of product prices:

import matplotlib.pyplot as plt

plt.figure(figsize=(10, 6))
plt.bar(df['Product Name'], df['Price'], color='skyblue')
plt.xlabel('Product Name')
plt.ylabel('Price (INR)')
plt.title('Product Prices Comparison')
plt.xticks(rotation=45, ha='right')
plt.tight_layout()
plt.show()

Result:
You’ll see a clear, visual comparison of prices, perfect for spotting deals or trends!

Best Practices for End-to-End Data Projects

• Respect websites: Follow robots.txt and terms of service.
• Handle errors: Use try-except for failed requests or parsing issues.
• Rate limiting: Add delays to avoid overloading servers.
• Store data securely: Save your cleaned data in CSV, JSON, or a database.
• Document your code: Add comments and keep your scripts organized.
• Automate ethically: Only scrape publicly available data and avoid sensitive or private information.
• Visualize responsibly: Always label axes and titles for clarity.
