Classical ML (not deep learning): tabular data, structured features, interpretable models, baseline modeling, feature engineering, cross-validation, and hyperparameter tuning.
Exploratory data analysis, correlation matrices, distribution comparisons, categorical plots, regression plots, or any time you want a beautiful statistical chart in a few lines.
Deep learning / neural networks (use PyTorch or TensorFlow), unstructured data like images or text at scale, real-time inference at very high throughput.
Custom non-statistical visualizations, interactive web charts, or when you need pixel-perfect control over layout.
