radialArea.context([context]) Equivalent to line.context.

radialArea.angle([angle]) Equivalent to area.x, except the accessor returns the angle in radians, with 0 at -y (12 o’clock).

radialArea(data) Equivalent to area.

queue.defer(task[, arguments…]) Adds the specified asynchronous task callback to the queue, with any optional arguments. The task is a function that will be called when the task should start. It is passed the specified optional arguments and an additional callback as the last argument; the callback must be invoked by the task when it finishes. The task must invoke the callback with two arguments: the error, if any, and the result of the task. To return multiple results from a single callback

queue.awaitAll(callback) Sets the callback to be invoked when all deferred tasks have finished. The first argument to the callback is the first error that occurred, or null if no error occurred. If an error occurred, there are no additional arguments to the callback. Otherwise, the callback is also passed an array of results as the second argument. For example: d3.queue() .defer(fs.stat, __dirname + "/../Makefile") .defer(fs.stat, __dirname + "/../package.json") .awaitAll(functio

queue.await(callback) Sets the callback to be invoked when all deferred tasks have finished. The first argument to the callback is the first error that occurred, or null if no error occurred. If an error occurred, there are no additional arguments to the callback. Otherwise, the callback is passed each result as an additional argument. For example: d3.queue() .defer(fs.stat, __dirname + "/../Makefile") .defer(fs.stat, __dirname + "/../package.json") .await(function(error, file1,

queue.abort() Aborts any active tasks, invoking each active task’s task.abort function, if any. Also prevents any new tasks from starting, and immediately invokes the queue.await or queue.awaitAll callback with an error indicating that the queue was aborted. See the introduction for an example implementation of an abortable task. Note that if your tasks are not abortable, any running tasks will continue to run, even after the await callback has been invoked with the abort error. The await ca

quantize.ticks([count]) Equivalent to continuous.ticks.

quantize.tickFormat([count[, specifier]]) Equivalent to continuous.tickFormat.

quantize.range([range]) If range is specified, sets the scale’s range to the specified array of values. The array may contain any number of discrete values. The elements in the given array need not be numbers; any value or type will work. If range is not specified, returns the scale’s current range.
