Animation visualizing the Bayesian Blocks dynamic programming algorithm for optimal histograms, inspired by Mike Bostock's Visualizing Algorithms. The algorithm is described in Studies in Astronomical Time Series Analysis. VI. Bayesian Block Representations.

For an example of Bayesian Blocks in action, see Bayesian Blocks Density Estimation.

(defmacro preval (&rest stuff) `(print ,stuff))

;;;; This Common Lisp macro is useful for debugging.

;;;; Rather than turning a statement like
;;;; (+ 2 3 (* 2 5))
;;;; into
;;;; (+ 2 3 (print (* 2 5)))
;;;; and back again for debugging, you can do this
;;;; (+ 2 3 (preval * 2 5))
