PathLayer

The deck.gl PathLayer displays lines composed of multiple segments, ideal for routes or boundaries. The path column contains a list of coordinates; ipydeck converts it to the format deck.gl expects.

from ipydeck import Deck, Layer, ViewState

waterfront = Layer(
    type="PathLayer",
    data=[
        {
            "name": "Embarcadero",
            "path": [
                [-122.397, 37.795],
                [-122.393, 37.806],
                [-122.399, 37.811],
                [-122.403, 37.808],
            ],
            "color": [255, 140, 0],
        }
    ],
    get_path="@@=path",
    get_color="@@=color",
    get_width=6,
    pickable=True,
)

Deck(
    layers=[waterfront],
    initial_view_state=ViewState(latitude=37.804, longitude=-122.399, zoom=13.5),
    tooltip={"text": "{name}"},
)

Enable rounded=True or width_units='pixels' to fine-tune the rendering for high-DPI displays.
