    Runs FEDOT on multimodal data from the `Wine Reviews dataset
    <https://www.kaggle.com/datasets/zynicide/wine-reviews>`_.
    The dataset contains information about wine country, region, price, etc.
    with text features in the ``description`` column and other columns containing
    numerical and categorical features. It is a classification task for wine variety prediction.

    Args:
        file_path: path to the file with multimodal data.
        visualization: if True, then final pipeline will be visualised.
        with_tuning: if True, then pipeline will be tuned.
