parv has asked for the wisdom of the Perl Monks concerning the following question:

Before I write a program to chart x-y values in plain text (again), does anyone know of any software|code to share which would spit out "scatter plot" on standard output (or in a file) in plain text (no image-graphs, Excel, LibreOffice, etc)?

I could not find something relevant here ("text plot"); on MetaCPAN; via DuckDuckGo.
