Jupyter notebooks combine Python callbacks and NumPy implementations to build interactive apps using ipywidgets and bqplot that run in real time. Examples include k‑means with 300 points and five clusters that shows local‑minima retries, gradient descent that diverges with high learning rates, Gaussian process regression with posterior bands, a tile‑map of the S&P 500's 500 constituents, a Wealth of Nations bubble/choropleth animator, and a Twitter sentiment dashboard trained on 100k tweets that exposes labeling errors via a confusion matrix and triangle plot. SVG rendering limits prevent plotting millions of points.
