Tangent to article: text character based charts for statistics. Decades ago I had an education version of MINITAB that ran under DOS and did scatter diagrams and dotplots and box and whisker plots from text characters (you could use pure text, I think proper ASCII or you could set an option to use those DOS drawing characters). The idea was to encourage initial data exploration before launching on formal statistical tests.

Anyone know of a terminal program that can do proper dotplots?
