    Args:
        direct_sun_study: A Ladybug-Radiance DirectSunStudy object.
        legend_parameters: An optional LegendParameter object to change the display
            of the direct sun study. If None, default legend parameters will be
            used. (Default: None).
        include_title: Boolean to note whether the title should be included
            in the output visualization. (Default: True).
        include_context: Boolean to note whether the context geometry should be
            included in the output visualization. (Default: False).

    Returns:
        A VisualizationSet with the direct sun study represented as an
        AnalysisGeometry. This includes these objects in the following order.

        -   Direct_Sun_Data -- An AnalysisGeometry for the direct sun data.

        -   Title -- A ContextGeometry with text for the title of the study.
                This layer will be excluded if include_title is False.
        
        -   Context_Geometry -- A ContextGeometry with the shading context used
                in the study. This layer will be excluded when include_context is False.
