Description

Groovy could provide an ascii barchart method. Python and DuckDB both provide methods for doing a simple barchart. Use would be something like this:

['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'].each{
  println "\n${it.padRight(12)}${bar(it.size(), 0, 10, 10)}"
}

With this output:

This isn't trying to be a fully-fledged chart package, just providing one simple option which can be handy when working with the console, command-line or groovysh.
