This example demonstrates how to automate the setup of a Go workspace and package installation via a shell script, following the official Go documentation. The script creates a temporary directory structure with a `src/newmath` folder and writes a custom `sqrt.go` file implementing a basic square root function. It then runs `go install example/newmath` to compile and install the package, verifying the result by checking for zero output or errors. The code relies on the Go command-line tool and standard shell utilities like `echo` and `mkdir`; no external visualization libraries are involved.
