wtf is figures-yann?

Figures-Yann is a collection of visual figures and illustrations created to accompany a book by someone named Yann. Rather than static images, these figures are built as interactive Jupyter Notebooks, documents that combine code, math, and visual output in a way that readers can view and even run themselves. The project includes a tool called jupytext, which keeps a plain Python file synced alongside each notebook. This makes the content easier to manage and version-track, since code changes can be compared line-by-line rather than inside a notebook's heavier file format. The most likely audience is readers or students of Yann's book who want to explore the figures interactively, or instructors who want to present them. The README doesn't go into detail about which book this supports or what topics the figures cover. Based on the author's background and the project's structure, the figures likely illustrate concepts in machine learning or deep learning, but the README itself doesn't specify this. One convenient detail: the project includes a Binder link, which lets anyone open and run the notebooks in their browser without installing anything locally. There's also an NbViewer link for simply viewing the notebooks read-only. This lowers the barrier considerably for non-technical readers who just want to see the visualizations. The project is small and narrowly focused, it exists to support a specific book rather than serve as a standalone tool. The README is minimal and doesn't provide guidance on contributing, prerequisites beyond jupytext, or how the figures map to chapters in the book.
