Mastering Julia - Second Edition

By: Malcolm Sherrington

Overview of this book

Julia is a well-constructed programming language which was designed for fast execution speed by using just-in-time LLVM compilation techniques, thus eliminating the classic problem of performing analysis in one language and translating it for performance in a second. This book is a primer on Julia’s approach to a wide variety of topics such as scientific computing, statistics, machine learning, simulation, graphics, and distributed computing. Starting off with a refresher on installing and running Julia on different platforms, you’ll quickly get to grips with the core concepts and delve into a discussion on how to use Julia with various code editors and interactive development environments (IDEs). As you progress, you’ll see how data works through simple statistics and analytics and discover Julia's speed, its real strength, which makes it particularly useful in highly intensive computing tasks. You’ll also and observe how Julia can cooperate with external processes to enhance graphics and data visualization. Finally, you will explore metaprogramming and learn how it adds great power to the language and establish networking and distributed computing with Julia. By the end of this book, you’ll be confident in using Julia as part of your existing skill set.

Visualization frameworks

A graphics framework provides a high-level interface to create complex visualizations as easily as possible. Ideally, we would like to acquire the data, specify a minimum of parametrization to identify the layout, labels, and so on, and pass these to a routine to produce the overall display with little (or no) knowledge of the underlying plotting methods.

Plotly/PlotlyJS

Plotly is a data analysis and graphing web application that can create precise and beautiful charts. It is based on D3 and, as such, incorporates a high degree of interaction such as hover text, panning, and zoom controls, as well as real-time data streaming options.

We will start by looking at PlotlyJS. It does not interact with the Plotly web API; instead, it uses the underlying JavaScript library to construct graphics using all local resources. This means that neither a Plotly account nor an internet connection is needed to use this package. However, plots can be uploaded into the...
