This PR fixes the inheritance diagrams rendering in the doc (that was shown as text).
Inheritance diagrams require
graphviz
to build. However,mamba
has trouble updating the baseenvironment.yml
withgraphviz
in the CI (that runs into two steps: base environment + update with dev packages), because some image-processing package dependencies are similar.To fix this, this PR explicitly adds
graphviz
when building the baseenvironment.yml
only in the CI.All other scripts building from
dev-environment.yml
are functioning fine (readthedocs, developper install).Also, it changes the color of edges to more adequately display inheritance diagrams in dark or light mode (background of text stays white, see: pydata/pydata-sphinx-theme#820)
Resolves #359
