graticule.step([step]) If step is specified, sets the major and minor step for this graticule. If step is not specified, returns the current minor step, which defaults to ⟨10°, 10°⟩.

graticule.precision([angle]) If precision is specified, sets the precision for this graticule, in degrees. If precision is not specified, returns the current precision, which defaults to 2.5°.

graticule.outline() Returns a GeoJSON Polygon geometry object representing the outline of this graticule, i.e. along the meridians and parallels defining its extent.

graticule.lines() Returns an array of GeoJSON LineString geometry objects, one for each meridian or parallel for this graticule.

graticule.extentMinor([extent]) If extent is specified, sets the minor extent of this graticule. If extent is not specified, returns the current minor extent, which defaults to ⟨⟨-180°, -80° - ε⟩, ⟨180°, 80° + ε⟩⟩.

graticule.extentMajor([extent]) If extent is specified, sets the major extent of this graticule. If extent is not specified, returns the current major extent, which defaults to ⟨⟨-180°, -90° + ε⟩, ⟨180°, 90° - ε⟩⟩.

graticule.extent([extent]) If extent is specified, sets the major and minor extents of this graticule. If extent is not specified, returns the current minor extent, which defaults to ⟨⟨-180°, -80° - ε⟩, ⟨180°, 80° + ε⟩⟩.

graticule() Returns a GeoJSON MultiLineString geometry object representing all meridians and parallels for this graticule.

gingery.radius([radius]) Defaults to 30°.

gingery.lobes([lobes]) Defaults to 6.
