A co-cone diagram (CCD) is a commuting diagram depicting maps (infomorphisms) $f_{ij}$ between classifiers ${\mathcal{A}}_i$ and ${\mathcal{A}}_j$, maps $g_{kl}$ from the ${\mathcal{A}}_k$ to one or more channels ${\mathcal{C}}_l$ over a subset of the ${\mathcal{A}}_i$, and maps $h_l$ from channels ${\mathcal{C}}_l$ to the colimit $\mathbf{C}$ (cf. Equation 6.7 of Ref. [35]). Adapted from Ref. [10] Figure 3, CC-BY license.
