Covers a practical EDA workflow that starts from raw CSV/text to cleaned features ready for models, demonstrating Python tools and exact functions: pandas DataFrame for isnull, dropna / fillna / drop_duplicates for missing and duplicate handling, outlier identification and removal, and scaling with StandardScaler / MinMaxScaler. Shows common plots (scatter, histogram, boxplot, heatmap, line, geo) and recommends iterating, documenting steps, and using scikit‑learn preprocessing and Plotly/Tableau for interactive checks; claims 0–1 normalization improves numeric stability for downstream models.
