Interactive Visualization and Plotting with Julia

By: Diego Javier Zea

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.

Understanding Makie’s layout system

We have already used some of Makie’s layout capabilities in the Interactive and reactive plots with Makie section of Chapter 3, Getting Interactive Plots with Julia. In this section, we will further discuss them. As we mentioned in the Knowing the components of Makie’s figures section of Chapter 10, The Anatomy of a Plot, a Figure object contains a GridLayout to indicate how to place the different layoutables in the final figure. Makie layoutables can be subplots, as in the case of Plots, or even other objects such as sliders and text, as shown in the example from Chapter 3, Getting Interactive Plots with Julia. Makie’s design gives us a lot of freedom when conceiving the arrangement of the different parts of the figure.

We can assign elements to one or multiple cells of a grid layout using the indexing syntax. For example, indexing a Figure object will select the indicated positions for its inner grid layout. We can...
