To create the flame graph in Chapter 10, Debugging Using LLVM Tools, you need to install the scripts from https://github.com/brendangregg/FlameGraph. To run the script, you also need a recent version of Perl installed, and to view the graph you need a web browser capable of displaying SVG files, which all modern browsers do. To see the Chrome Trace Viewer visualization in the same chapter, you need to have the Chrome browser installed.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
