        **kwargs,
    )
    Docstring:     
    Create a simple stock Leaflet marker on the map, with optional
    popup text or Vincent visualization.
    
    Parameters
    ----------
    location: tuple or list
        Latitude and Longitude of Marker (Northing, Easting)
    popup: string or folium.Popup, default None
        Label for the Marker; either an escaped HTML string to initialize
        folium.Popup or a folium.Popup instance.
    tooltip: str or folium.Tooltip, default None
        Display a text when hovering over the object.
    icon: Icon plugin
        the Icon plugin to use to render the marker.
    draggable: bool, default False
        Set to True to be able to drag the marker around the map.
    
    
    Init signature: folium.Polygon(locations, popup=None, tooltip=None, **kwargs)
    Docstring:     
    Draw polygon overlays on a map.
    
    See :func:`folium.vector_layers.path_options` for the `Path` options.
    
    Parameters
    ----------
    locations: list of points (latitude, longitude)
        Latitude and Longitude of line (Northing, Easting)
    popup: string or folium.Popup, default None
        Input text or visualization for object displayed when clicking.
    tooltip: str or folium.Tooltip, default None
        Display a text when hovering over the object.
    **kwargs
        Other valid (possibly inherited) options. See:
        https://leafletjs.com/reference-1.6.0.html#polygon
    
    
    Init signature: folium.PolyLine(locations, popup=None, tooltip=None, **kwargs)
    Docstring:
