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.

Makie’s Algebra of Graphics

The AlgebraOfGraphics package is another Julia implementation of the Grammar of Graphics. It renders the plots using Makie. Therefore, you need to load a Makie backend, such as CairoMakie, to work with it. The grammar of the Algebra of Graphics has the following main components:

  • Data: The data function indicates the dataset to be used.
  • Mapping: AlgebraOfGraphics uses the mapping function to indicate the mapping between data variables and aesthetics. The first three positional arguments designate the variables that have been mapped to the x, y, and z positions. The mapping function maps other aesthetics, such as color and markersize, using keyword arguments. The function also implements a pair syntax for transformations of the data.
  • Visual: This is related to geometry on other grammar implementations as it designates what type of named plot we are creating. AlgebraOfGraphics uses the visual function to indicate a Makie named plot using...
