Matplotlib & Seaborn Practice Workbook

Build real plotting fluency on TechNest Retail, a synthetic e-commerce dataset with 4,012 orders over two years — including the missing values, duplicate orders and inconsistent labels you meet in real data.

A learning phase walks through Matplotlib and Seaborn one concept at a time, a testing phase makes you choose the right chart yourself — with debugging and "is this chart misleading?" questions — and a final challenge builds an executive one-page dashboard. Hints and full solutions are on request.
