Fig. 1.

Topological map of information propagation in an experimental diffusion chain. Among all units of information available at chain position 1 (blue dots), only three have survived to the end of the chain, although they were strongly distorted. The text on the right-hand side describes the categories of these units of information. Seven units of information were introduced by the chain (squares), two of which survived to the end of the chain. The color coding indicates the cumulated content distortion of the information. Information identifications (y axis) are arbitrary.
