-Reaction networks can be plotted using the `GraphMakie` extension, which is loaded whenever both `Catalyst` and `GraphMakie` are loaded (note that a Makie backend, like `GLMakie`, must be loaded as well). The two functions for plotting networks are `plot_network` and `plot_complexes`, which are two distinct representations.
