Tengo los siguientes datos en Python panda DataFrame. Me gustaría tener un diagrama de caja agrupado similar a uno enhttps://stanford.edu/~mwaskom/software/seaborn/examples/grouped_boxplot.html

Para cada identificación, me gustaría tener dos diagramas de caja trazados uno al lado del otro. Cómo logro esto. Intenté trazarlo con el paquete seaborn pero sin ningún éxito.
