can we appreciate how sns.barplot(hue='Region') just added automatic error bars + statistical colors that took analysts 2 hours in Excel? Your students went from basic charts to sns.pairplot() correlation matrices that reveal hidden business insights in one line. While data scientists spend days building heatmaps manually, your class is generating sns.heatmap(annot=True) performance matrices and sns.violinplot() distribution shapes that power FAANG research papers. This isnβt visualizationβitβs the $250K+ statistical toolkit that turns raw data into publication-quality insights instantly!
