Constructs a Pareto chart. Data can be inserted manually or, more simply, via copy and paste from source documents, such as an Excel sheet or a 'pdf' file. (Example data.xlsx...) Category text in non-ASCII characters (such as in Latin languages) may misalign the data tables (without other consequences).

A graph is drawn showing the Pareto chart, with the absolute and relative frequencies.
