histogram_bins: Optional[int] = Query(None, description="Histogram bins.")

bins (int or sequence of scalars or str, optional)
If bins is an int, it defines the number of equal-width bins in the given range (10, by default). If bins is a sequence, it defines a monotonically increasing array of bin edges, including the rightmost edge, allowing for non-uniform bin widths.
