Agentic Data Science: code examples

Runnable, tested code examples for the Agentic Data Science specialization by Pragmatic AI Labs: the same four data science problems solved in five languages with an AI coding agent in the loop, under strict quality gates.

The five courses

Course	Language
C	R
B	Julia
D	Kotlin
A	Rust
E	Lean 4

Specialization: https://www.coursera.org/specialization/agentic-data-science (link goes live at launch).

Layout

• datasets/: Palmer Penguins and UCI Wine Quality, each with LICENSE and SHA256SUMS; fixed folds, splits and centroids in fixtures/; golden reference numbers in golden/.
• ontology/: vocabulary and SHACL shapes that every example's example.ttl must satisfy.
• Language packages (r/, julia/, kotlin/, rust/, lean/) are added as each course's examples land.
