Publishers: plot with Plotly

publish_plotly.py

"""Example: Publishers: plot with Plotly.

Plots a simulated PSU voltage sweep on a Plotly figure with PlotlyPublisher, then
shows the figure once the sweep finishes. In a Jupyter notebook, display a
``go.FigureWidget`` instead to watch the plot update live.

Requires the plot extra: install with ``uv sync --extra plot``
(or ``pip install 'instro[plot]'``).

Start the simulated PSU first:
    python -m instro.psu.scpi_sim_server

Then in another shell:
    python examples/publishers/publish_plotly.py
