Hooks into Catalyst's Graphviz interface to allow for plotting CRN graphs directly from
SpeciesData
/RxData
CRNs.This required a bit of a rewrite of Catalyst's main graphing function, as it doesn't support working with
ReactionSystem
s based on Symbolics.jl's 'arrays of symbolic expressions' (see here for more details) due to missing name fields for species symbols.This also adds onto the functionality present in Catalyst by allowing for passing Graphviz attributes through to the plotter, enabling greater customisability and, very importantly, a choice of layout engine since Catalyst's default for directed graphs (
dot
) scales very poorly to large CRNs.
