Paste raw numbers (one per line or comma/space separated) and get a proper Tukey box plot with Q1, median, Q3, IQR fences, mild and extreme outliers, and a full five-number summary. Compare multiple groups by separating them with a blank line.
Quartiles use linear interpolation (Tukey / type-7). Fences: Q1 − 1.5·IQR and Q3 + 1.5·IQR for mild outliers, ±3·IQR for extreme.
