json2dsv [options…] [file] Converts the specified JSON input file to DSV. If file is not specified, defaults to reading from stdin. For example, to convert to JSON to CSV: json2csv < example.json > example.csv Or to convert a newline-delimited JSON stream to CSV: json2csv -n < example.ndjson > example.csv

transition.remove() For each selected element, removes the element when the transition ends, as long as the element has no other active or pending transitions. If the element has other active or pending transitions, does nothing.

tile.translate([translate]) If translate is specified, sets this tile layout’s translate to the specified two-element array of numbers [x, y] and returns this tile layout. If translate is not specified, returns the current layout translate.

d3.timeMonth d3.utcMonth Months (e.g., February 1, 2012 at 12:00 AM); ranges from 28 to 31 days.

d3.geoStream(object, stream) Streams the specified GeoJSON object to the specified projection stream. While both features and geometry objects are supported as input, the stream interface only describes the geometry, and thus additional feature properties are not visible to streams.

d3.format(specifier) An alias for locale.format on the default locale.

d3.geoPolyhedralButterfly() The gnomonic butterfly projection.

simulation.velocityDecay([decay]) If decay is specified, sets the velocity decay factor to the specified number in the range [0,1] and returns this simulation. If decay is not specified, returns the current velocity decay factor, which defaults to 0.4. The decay factor is akin to atmospheric friction; after the application of any forces during a tick, each node’s velocity is multiplied by 1 - decay. As with lowering the alpha decay rate, less velocity decay may converge on a better solution,

map.remove(key) If the map has an entry for the specified key string, removes the entry and returns true. Otherwise, this method does nothing and returns false.

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⟩⟩.
