A. Partition examples for the start of Charles Dickens’s “Tale of Two Cities” at five distinct levels: clauses (red), pure random partitioning phrases (, orange), words (yellow), pure random partitioning graphemes (, green), and letters (blue). The specific phrases and graphemes shown are for one realization of pure random partitioning. B. Zipf distributions for the five kinds of partitions along with estimates of the Zipf exponent θ when scaling is observed. No robust scaling is observed at the letter scale. The colors match those used in panel A, and the symbols at the start of each distribution are intended to strengthen the connection to the legend. See Ref. 28 and the Supplementary Information for measurement details.
