d3.geoAitoff() d3.geoAitoffRaw The Aitoff projection.

d3.geoAiry() d3.geoAiryRaw(beta) Airy’s minimum-error azimuthal projection.

d3.formatSpecifier(specifier) Parses the specified specifier, returning an object with exposed fields that correspond to the format specification mini-language and a toString method that reconstructs the specifier. For example, formatSpecifier("s") returns: { "fill": " ", "align": ">", "sign": "-", "symbol": "", "zero": false, "width": undefined, "comma": false, "precision": 6, "type": "s" } This method is useful for understanding how format specifiers are parsed and for

d3.formatPrefix(specifier, value) An alias for locale.formatPrefix on the default locale.

d3.formatLocale(definition) Returns a locale object for the specified definition with locale.format and locale.formatPrefix methods. The definition must include the following properties: decimal - the decimal point (e.g., "."). thousands - the group separator (e.g., ","). grouping - the array of group sizes (e.g., [3]), cycled as needed. currency - the currency prefix and suffix (e.g., ["$", ""]). Note that the thousands property is a misnomer, as the grouping definition allows groups o

d3.formatDefaultLocale(definition) Equivalent to d3.formatLocale, except it also redefines d3.format and d3.formatPrefix to the new locale’s locale.format and locale.formatPrefix. If you do not set a default locale, it defaults to U.S. English.

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

d3.forceY([y]) Creates a new positioning force along the y-axis towards the given position y. If y is not specified, it defaults to 0.

d3.forceX([x]) Creates a new positioning force along the x-axis towards the given position x. If x is not specified, it defaults to 0.

d3.forceSimulation([nodes]) Creates a new simulation with the specified array of nodes and no forces. If nodes is not specified, it defaults to the empty array. The simulator starts automatically; use simulation.on to listen for tick events as the simulation runs. If you wish to run the simulation manually instead, call simulation.stop, and then call simulation.tick as desired.
