create_streaming_plot
Create a real-time streaming chart that updates client-side with simulated data or replays a dataset progressively. Outputs a self-contained HTML page with no server required.
Instructions
Create a live-updating streaming visualization with simulated real-time data.
The output is a self-contained HTML page with Panel periodic callbacks that simulates streaming data — the chart updates in real time. This works entirely client-side, no server needed.
If a dataset is provided, the streaming simulation replays its data progressively. Otherwise, generates a random walk time series.
