This example demonstrates how to execute Ruby code in various ways from the command line, showing both interactive and script-based approaches. It highlights the use of `ruby` for one-liners, `irb` for interactive sessions, and file execution with shebang lines. The visualization uses text output to illustrate each method, relying on standard shell commands like `cat`, `chmod`, and `which` to show file creation, permissions, and environment setup. The data is the terminal output from each command, rendered as plain text in a terminal-like format.
