To display graphics... you first need a window !

If you want to display pixels, lines, use ruby-opengl, your code will
execute everywhere.

If you need controls, you need some platform specific library or
something like Ruby/Tk.

require 'tk'
root = TkRoot.new() { title "Hello, world!" }
Tk.mainloop()
