Plotting

Visualization functions with a clean, minimalist style. All functions are called internally by DLM.plot() but can also be used standalone.

• plot_filtered — observed data with filtered state overlay

• plot_smoothed — smoothed state estimates with confidence bands

• plot_components — decomposition into individual state components

• plot_forecast — forecast fan chart with historical context

• plot_diagnostics — QQ-plot, ACF, and histogram of residuals
