Until pygraphviz/pygraphviz#573 is resolved it is not possible to pip install pygraphviz.
To resolve this, in #5085 we skip the tape visualisation step in the adjoint demo and remove pygraphviz from the set of dependencies we install on CI and our Docker containers.
Once the upstream issue is fixed we should add pygraphviz back in.
