Fisher's paper was published in the journal, the Annals of Eugenics, creating controversy about the continued use of the Iris dataset for teaching statistical techniques today.

One of the points of the paper (and of the journal, and of Fisher’s leading role in developing biometry and biostatistics) was to propose a methodological framework to delineate desirable traits, in support of eugenics programs. One does not publish in the Annals of Eugenics in 1936 on a misunderstanding.

A penguin-based alternative: https://twitter.com/allison_horst/status/1270046399418138625 https://allisonhorst.github.io/palmerpenguins/articles/pca.html

Palmer Penguins is an R package but there are instructions for using it in Python here: https://towardsdatascience.com/data-analysis-in-python-getting-started-with-pandas-8cbcc1500c83 I understand that pandas is banned here, but I'd be shocked if this hasn't been added into a package that is already used (and if it hasn't, could it be?)

Other non-penguin based alternatives are probably also available.

Penguins is indeed very fun and serves the same pedagogical goals.
