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.

Knowing the components of Makie’s figures

In Makie, we can think of the Figure object as the main plot element. It contains a GridLayout that will determine the location of the different plot components in the figure. Therefore, Makie’s Figure is similar to the plot object from Plots. The pieces we can arrange on GridLayout are called layoutables. We can find Axis, Label, Legend, and Colorbar among the many layoutables available. While Plots locates most of those elements in the subplots, Makie gives us the freedom to arrange them in Figure. We will learn more about how to place layoutables in Makie’s GridLayout in Chapter 11, Defining Plot Layouts to Create Figure Panels.

The Axis layoutable object contains the axes for our plot, and we plot our data in it. Makie axes components are similar to those of the Plots package, which we saw in the previous section. Axis objects include the spines and the decorations: the x- and y-axis labels, the ticks and grid, and...
