Overview of this book

Jupyter Notebook is a web-based environment that enables interactive computing in notebook documents. It allows you to create and share documents that contain live code, equations, visualizations, and explanatory text. The Jupyter Notebook system is extensively used in domains such as data cleaning and transformation, numerical simulation, statistical modeling, machine learning, and much more. This book starts with a detailed overview of the Jupyter Notebook system and its installation in different environments. Next we’ll help you will learn to integrate Jupyter system with different programming languages such as R, Python, JavaScript, and Julia and explore the various versions and packages that are compatible with the Notebook system. Moving ahead, you master interactive widgets, namespaces, and working with Jupyter in a multiuser mode. Towards the end, you will use Jupyter with a big data set and will apply all the functionalities learned throughout the book.

Julia Vega plotting

Another popular graphics package is Vega. The main feature of Vega is the ability to describe your graphic using language primitives, such as JSON. Vega produces most of the standard plots. Here is an example script using Vega for a pie chart:

using Vega
using Compat
using Patchwork
stock = ["chairs", "tables", "desks", "rugs", "lamps"];
quantity = [15, 10, 10, 5, 20];
piechart(x = stock, y = quantity)

The generated graphic produced in Jupyter is shown in the following screenshot:


Vega gives you the option on the resultant display to Save As PNG.

Julia PyPlot plotting

Another plotting package available is PyPlot. PyPlot is one of the standard Python visualization libraries and is directly accessible from Julia. We can take this small script to produce an interesting visualization:

using PyPlot
precipitation = [0,0,0,0,0,0,0,0,0,0,0.12,0.01,0,0,0,0.37,0,0,0,0,
