Overview of this book

In this first-of-its-kind TikZ book, you’ll embark on a journey to discover the fascinating realm of TikZ—what it’s about, the philosophy behind it, and what sets it apart from other graphics libraries. From installation procedures to the intricacies of its syntax, this comprehensive guide will help you use TikZ to create flawless graphics to captivate your audience in theses, articles, or books. You’ll learn all the details starting with drawing nodes, edges, and arrows and arranging them with perfect alignment. As you explore advanced features, you’ll gain proficiency in using colors and transparency for filling and shading, and clipping image parts. You’ll learn to define TikZ styles and work with coordinate calculations and transformations. That’s not all! You’ll work with layers, overlays, absolute positioning, and adding special decorations and take it a step further using add-on packages for drawing diagrams, charts, and plots. By the end of this TikZ book, you’ll have mastered the finer details of image creation, enabling you to achieve visually stunning graphics with great precision.

Drawing trees

Trees are a specific kind of graph where any two vertices are connected by exactly one path, which consists of edges. We may encounter them in mathematics, such as in graph theory, in computer science, or in any drawing that illustrates parent-children relationships in a hierarchical way.

We already know the node and edge operations, and the child operation combines both of them. Specifically, it connects a parent node and one or more child nodes by edges, each from the parent to a child. Moreover, TikZ counts the children and determines an appropriate positioning for each of them.

A very simple example is this:

\node {A} child { node {1} edge from parent };

The output is this very simple tree:

edge from parent is a special path operation that adds an edge from the parent to the child. We can add options and nodes to this edge, as we know from Chapter 4, Drawing Edges and Arrows. For example,...
