graticule.stepMajor([step]) If step is specified, sets the major step for this graticule. If step is not specified, returns the current major step, which defaults to ⟨90°, 360°⟩.

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

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

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

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

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

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⟩⟩.
