%description
Provides a suite of helper functions and a collection of datasets used in
the book <https://uncovering-data-science.netlify.app>. It is designed to
make data science techniques accessible to individuals with minimal coding
experience. Inspired by an ancient Persian idiom, the package likens this
learning process to "eating the liver of data science," symbolizing deep
and immersive engagement with the field.
