rhiever/Data-Analysis-and-Machine-Learning-Projects ? reverse-engineered prompt

Build me a simple GitHub repository of data analysis and machine learning examples like a teaching notebook collection.

I want a clean set of Jupyter notebooks, with one notebook and any needed data or code in each topic folder, so someone can open them and learn from real examples. Make the README friendly and clear, explain what each project is about, and note that people can view the notebooks online if they do not have the setup installed locally. Include a basic environment file so the notebooks are easy to run, and keep the whole thing organized for things like visualization, optimization, and machine learning demos.

Use plain Python and notebook based examples, and make it feel like a polished collection of reusable learning projects rather than a single app. If you need to check current notebook or package docs online while building it, go ahead.
