Projection configuration, which determines default properties for all projections. For a full list of projection configuration options, please see the corresponding section of the projection documentation.

Any property of Projection can be in config

An object defining properties of geographic projection, which will be applied to shape path for "geoshape" marks and to latitude and "longitude" channels for other marks.

An object defining properties of the geographic projection shared by underlying layers.

Fields

center: Option<Vec<f64>>

The projection’s center, a two-element array of longitude and latitude in degrees.

Default value: [0, 0]

clip_angle: RemovableValue<f64>

The projection’s clipping circle radius to the specified angle in degrees. If null, switches to antimeridian cutting rather than small-circle clipping.

clip_extent: RemovableValue<Vec<Vec<f64>>>

The projection’s viewport clip extent to the specified bounds in pixels. The extent bounds are specified as an array [[x0, y0], [x1, y1]], where x0 is the left-side of the viewport, y0 is the top, x1 is the right and y1 is the bottom. If null, no viewport clipping is performed.

coefficient: Option<f64>

distance: Option<f64>

extent: Option<Vec<Vec<f64>>>

fit: Option<Value>

fraction: Option<f64>

lobes: Option<f64>

parallel: Option<f64>

parallels: Option<Vec<f64>>

For conic projections, the two standard parallels that define the map layout. The default depends on the specific conic projection used.

point_radius: Option<f64>

The default radius (in pixels) to use when drawing GeoJSON Point and MultiPoint geometries. This parameter sets a constant default value. To modify the point radius in response to data, see the corresponding parameter of the GeoPath and GeoShape transforms.

Default value: 4.5

precision: Option<f64>

The threshold for the projection’s adaptive resampling to the specified value in pixels. This value corresponds to the Douglas–Peucker distance. If precision is not specified, returns the projection’s current resampling precision which defaults to √0.5 ≅ 0.70710….

radius: Option<f64>

ratio: Option<f64>

reflect_x: Option<bool>

reflect_y: Option<bool>

rotate: Option<Vec<f64>>

The projection’s three-axis rotation to the specified angles, which must be a two- or three-element array of numbers [lambda, phi, gamma] specifying the rotation angles in degrees about each spherical axis. (These correspond to yaw, pitch and roll.)

Default value: [0, 0, 0]

scale: Option<f64>

The projection’s scale (zoom) factor, overriding automatic fitting. The default scale is projection-specific. The scale factor corresponds linearly to the distance between projected points; however, scale factor values are not equivalent across projections.

size: Option<Vec<f64>>

spacing: Option<f64>

tilt: Option<f64>

translate: Option<Vec<f64>>

The projection’s translation offset as a two-element array [tx, ty].

projection_type: Option<ProjectionType>

The cartographic projection to use. This value is case-insensitive, for example "albers" and "Albers" indicate the same projection type. You can find all valid projection types in the documentation.

Default value: mercator
