d3.variance()

d3.variance(array[, accessor])

Returns an unbiased estimator of the population variance of the given array of numbers. If the array has fewer than two values, returns undefined. An optional accessor function may be specified, which is equivalent to calling array.map(accessor) before computing the variance. This method ignores undefined and NaN values; this is useful for ignoring missing data.
