Technical requirements
As with every chapter, you need to have a LaTeX installation, including TikZ, or you can work online with Overleaf or work with the code at https://tikz.org/chapter-05.
The code is also available on GitHub at https://github.com/PacktPublishing/LaTeX-graphics-with-TikZ/tree/main/05-using-styles-and-pics.
In this chapter, we will use the positioning
and scope
TikZ libraries and the tikzlings
package.
