Data Visualization with Python and JavaScript, 2nd Edition

Python provides accessible, powerful, and mature libraries for scraping, cleaning, and processing data. And while JavaScript is the best language when it comes to programming web visualizations, its data processing abilities can't compare with Python's. Together, these two languages are a perfect complement for creating a modern web-visualization toolchain. This book gets you started.

You'll learn how to:

• Obtain data you need programmatically, using scraping tools or web APIs: Requests, Scrapy, Beautiful Soup
• Clean and process data using Python's heavyweight data processing libraries within the NumPy ecosystem: Jupyter notebooks with pandas+Matplotlib+Seaborn
• Deliver the data to a browser with static files or by using Flask, the lightweight Python server, and a RESTful API
• Pick up enough web development skills (HTML, CSS, JS) to get your visualized data on the web
• Use the data you've mined and refined to create web charts and visualizations with Plotly, D3, Leaflet, and other libraries
