snailz 5.0.1

Synthetic data generator for snail mutation survey

Snailz

snailz is a synthetic data generator that models a study of snails in the Pacific Northwest which are growing to unusual size as a result of exposure to pollution. The package generates fully-reproducible datasets of varying sizes and with varying statistical properties, and is intended for classroom use. For example, an instructor can give each learner a unique dataset to analyze, while learners can test their analysis pipelines using datasets they generate themselves.

The Story

Years ago, logging companies dumped toxic waste in a remote region of Vancouver Island. As the containers leaked and the pollution spread, some snails in the region began growing unusually large. Your team is now collecting and analyzing specimens from affected regions to determine if exposure to pollution is responsible.

Colophon

snailz was inspired by the Palmer Penguins dataset and by conversations with Rohan Alexander about his book Telling Stories with Data.

My thanks to everyone who built the tools this project relies on, including:

• faker for synthesizing data.
• mkdocs for documentation.
• ruff for checking the code.
• sqlite and sqlite-utils for persistence.
• taskipy for running tasks.
• uv for managing packages and the virtual environment.

The snail logo was created by sunar.ko.
