    An array of lng,lat arrays.

    Example: 2 point line

    [[-104.984855, 39.738452], [-105.279266, 40.01583]]

  • color string

    rgb, hex, or color name for the line.

  map.fitBounds();
});

Parameters

  • points required array of multiple [lng, lat]

    An array of lng,lat arrays.

    Example: 2 point polygon

  map.fitBounds();
});

Parameters
