Escher.jl is a small recipe package that plots metabolic networks and their associated data using the awesome Makie. In short, metabolic maps, like those found on the website Escher, can be plotted from the comfort of Julia.
Using Escher.jl, you can generate metabolic maps that look like this (see the readme for the associated code):
Core model map (metabolites/nodes and reactions/edges are colored/sized)
iJO1366 model map (only fluxes)
The labels associated with reactions and metabolites can also be added using built in attributes, but for aesthetic purposes, I left those out
