Book6_First-Course-in-Data-Science

Why we included this project

The sixth volume of the Iris series is a Chinese-language textbook that builds from basic arithmetic up to practical machine learning, and it does that visually. The repository is a collection of Jupyter notebooks and vector graphics, so concepts like missing values, feature engineering, time series, and graph analysis come with runnable code and figures you can follow line by line. That makes it a solid pick for learners who want an intuition-first route into data science rather than a conventional dry textbook. It also works as a refresher for developers who already use pandas and scikit-learn but want to firm up the underlying ideas. The material is released free as open educational content alongside a commercially published edition, so it doubles as a low-cost curriculum for self-study or a course.
