class BarConfig(PlotlyBaseConfig):
    """
    Pydantic model for validating and managing bar plot configurations,
    which extends PlotlyBaseConfig.

    This model serves as a curated API for the most relevant parameters
    for bar plots, closely aligned with the `plotly.express.bar` API
    (https://plotly.com/python-api-reference/generated/plotly.express.bar.html).

    This model includes the most relevant parameters for data mapping, styling,
    and layout. It ensures that user-provided configurations are type-safe and
    adhere to the expected structure. The plotting function handles parameters
    defined here, and also accepts additional Plotly keyword arguments,
    forwarding them to the appropriate `plotly.express.bar` or
    `plotly.graph_objects.Figure` call.
