LineLayer

The deck.gl LineLayer renders straight lines between coordinates. Configure widths and colors using the standard accessor props.

from ipydeck import Deck, Layer, ViewState

bike_routes = Layer(
    type="LineLayer",
    data=[
        {
            "start": [-122.425, 37.77],
            "end": [-122.412, 37.785],
            "color": [34, 139, 34],
        },
        {
            "start": [-122.404, 37.79],
            "end": [-122.401, 37.793],
            "color": [70, 130, 180],
        },
    ],
    get_source_position="@@=start",
    get_target_position="@@=end",
    get_color="@@=color",
    get_width=5,
    pickable=True,
)

Deck(
    layers=[bike_routes],
    initial_view_state=ViewState(latitude=37.78, longitude=-122.41, zoom=13),
    tooltip={"text": "Segment"},
)

Swap in great_circle=True when you need to draw curved connections instead of straight segments.
