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.

Chapter 9: Plotting Biological Data

Technical advancements, such as new sequencing technologies or machine learning algorithms, are driving a revolution in biology. That revolution is expanding the fields of bioinformatics and computational biology. The large amount of biological data we are generating nowadays also pushes innovation on the data visualization front. Interactive visualizations are essential for navigating such extensive and complex data. Biological information is also highly heterogeneous; we can have sequences, medical images, and geographical locations, to name a few. Biological data visualization is a vast subject, from which we will only explore ways to visualize phylogenetic trees and protein sequences and structures in this chapter. However, the Julia ecosystem has more tools for analyzing and visualizing biological data. You can explore some of those tools in the BioJulia, JuliaHealth, and EcoJulia organizations.

In this chapter, we will learn how to visualize...
