        Create a Map object.

        Args:
            center (tuple, optional): The center of the map (lon, lat). Defaults
                to (0, 20).
            zoom (float, optional): The zoom level of the map. Defaults to 1.
            pitch (float, optional): The pitch of the map. Measured in degrees
                away from the plane of the screen (0-85) Defaults to 0.
            bearing (float, optional): The bearing of the map. Measured in degrees
                counter-clockwise from north. Defaults to 0.
            style (str, optional): The style of the map. It can be a string or a URL.
                If it is a string, it must be one of the following: "dark-matter", "positron",
                "carto-positron", "voyager", "positron-nolabels", "dark-matter-nolabels",
                "voyager-nolabels", "demotiles", "liberty", "bright", or "positron2".
                If a MapTiler API key is set, you can also use any of the MapTiler styles,
                such as aquarelle, backdrop, basic, bright, dataviz, landscape, ocean,
                openstreetmap, outdoor, satellite, streets, toner, topo, winter, etc.
                If it is a URL, it must point to a MapLibre style JSON. Defaults to "dark-matter".
            height (str, optional): The height of the map. Defaults to "600px".
            controls (dict, optional): The controls and their positions on the

            projection (str, optional): The projection of the map. It can be
                "mercator" or "globe". Defaults to "mercator".
            use_message_queue (bool, optional): Whether to use the message queue.
                Defaults to None. If None, it will check the environment variable
                "USE_MESSAGE_QUEUE". If it is set to "True", it will use the message queue, which
                is needed to export the map to HTML. If it is set to "False", it will not use the message
                queue, which is needed to display the map multiple times in the same notebook.
            add_sidebar (bool, optional): Whether to add a sidebar to the map.
                Defaults to True. If True, the map will be displayed in a sidebar.
            sidebar_visible (bool, optional): Whether the sidebar is visible. Defaults to False.
            sidebar_width (int, optional): The width of the sidebar in pixels. Defaults to 360.
            sidebar_args (dict, optional): The arguments for the sidebar. It can
                be a dictionary with the following keys: "sidebar_visible", "min_width",
                "max_width", and "sidebar_content". Defaults to None. If None, it will
                use the default values for the sidebar.
            layer_manager_expanded (bool, optional): Whether the layer manager is expanded. Defaults to True.
            **kwargs: Additional keyword arguments that are passed to the MapOptions class.

__init__(center=(0, 20), zoom=1, pitch=0, bearing=0, style='dark-matter', height='600px', controls={'navigation': 'top-right', 'fullscreen': 'top-right', 'scale': 'bottom-left', 'globe': 'top-right'}, projection='mercator', use_message_queue=None, add_sidebar=True, sidebar_visible=False, sidebar_width=360, sidebar_args=None, layer_manager_expanded=True, **kwargs)

Create a Map object.

Parameters:

Name Type Description Default
center tuple

The center of the map (lon, lat). Defaults to (0, 20).

(0, 20)
zoom float

The zoom level of the map. Defaults to 1.

1
pitch float

The pitch of the map. Measured in degrees away from the plane of the screen (0-85) Defaults to 0.

0
bearing float

The bearing of the map. Measured in degrees counter-clockwise from north. Defaults to 0.

0
style str

The style of the map. It can be a string or a URL. If it is a string, it must be one of the following: "dark-matter", "positron", "carto-positron", "voyager", "positron-nolabels", "dark-matter-nolabels", "voyager-nolabels", "demotiles", "liberty", "bright", or "positron2". If a MapTiler API key is set, you can also use any of the MapTiler styles, such as aquarelle, backdrop, basic, bright, dataviz, landscape, ocean, openstreetmap, outdoor, satellite, streets, toner, topo, winter, etc. If it is a URL, it must point to a MapLibre style JSON. Defaults to "dark-matter".

'dark-matter'
height str

The height of the map. Defaults to "600px".

'600px'
controls dict

The controls and their positions on the map. Defaults to {"fullscreen": "top-right", "scale": "bottom-left"}.

{'navigation': 'top-right', 'fullscreen': 'top-right', 'scale': 'bottom-left', 'globe': 'top-right'}
projection str

The projection of the map. It can be "mercator" or "globe". Defaults to "mercator".

'mercator'
use_message_queue bool

Whether to use the message queue. Defaults to None. If None, it will check the environment variable "USE_MESSAGE_QUEUE". If it is set to "True", it will use the message queue, which is needed to export the map to HTML. If it is set to "False", it will not use the message queue, which is needed to display the map multiple times in the same notebook.

None
add_sidebar bool

Whether to add a sidebar to the map. Defaults to True. If True, the map will be displayed in a sidebar.

True
sidebar_visible bool

Whether the sidebar is visible. Defaults to False.

False
sidebar_width int

The width of the sidebar in pixels. Defaults to 360.

360
sidebar_args dict

The arguments for the sidebar. It can be a dictionary with the following keys: "sidebar_visible", "min_width", "max_width", and "sidebar_content". Defaults to None. If None, it will use the default values for the sidebar.

None
layer_manager_expanded bool

Whether the layer manager is expanded. Defaults to True.

True
**kwargs Any

Additional keyword arguments that are passed to the MapOptions class. See https://maplibre.org/maplibre-gl-js/docs/API/type-aliases/MapOptions/ for more information.
