Overview of this book

The Julia programming language offers a fresh perspective into the data visualization field. Interactive Visualization and Plotting with Julia begins by introducing the Julia language and the Plots package. The book then gives a quick overview of the Julia plotting ecosystem to help you choose the best library for your task. In particular, you will discover the many ways to create interactive visualizations with its packages. You’ll also leverage Pluto notebooks to gain interactivity and use them intensively through this book. You’ll find out how to create animations, a handy skill for communication and teaching. Then, the book shows how to solve data analysis problems using DataFrames and various plotting packages based on the grammar of graphics. Furthermore, you’ll discover how to create the most common statistical plots for data exploration. Also, you’ll learn to visualize geographically distributed data, graphs and networks, and biological data. Lastly, this book will go deeper into plot customizations with Plots, Makie, and Gadfly—focusing on the former—teaching you to create plot themes, arrange multiple plots into a single figure, and build new plot types. By the end of this Julia book, you’ll be able to create interactive and publication-quality static plots for data analysis and exploration tasks using Julia.

Using LaTeX equations

When plotting with Plots and Makie, we can use LaTeX equations created with the LaTeXStrings package. In particular, we can use the L string macro, @L_str, to create such equations. When using Plots, we will need to load the LaTeXStrings package to use the L string macro. Loading that package is unnecessary when using Makie, as Makie automatically exports that macro. The syntax is simple; you only need to write your LaTeX equation inside a string and add an L prefix before the quotation mark, as shown in the following line of code:

L"x^2 + y^2 = 1"

When we create a LaTeXString object using the L string macro, as in the previous code, we do not need to enclose the equation within the dollar symbols. However, you can use them to add an equation inside a longer string, as shown in the following example:

L"Unit circle: $x^2 + y^2 = 1$"

As the dollar symbol, $, has a special meaning inside LaTeX strings, we will need to use %$ to interpolate...
