Since fc58f8b0d597ee10c82051bf6bbbe7706bbc5879, builds of the public documentation fails because it can't install swh-graph from PyPI: https://jenkins.softwareheritage.org/view/all/job/DDOC/job/publish/253/console
Sure, let's do that, but I've never touched anything related to SWH on PyPI, so I've no idea how to make it happen.
Whoever has an idea of how do to that, please just go ahead. (And feel free to tag any recent version for PyPI publishing; the currently tagged version was completely arbitrary, just because a tag was needed for $something.)
However in swh-docs the java version is 8 which is not compatible to generate the javadoc (it should be >= 9), see https://jenkins.softwareheritage.org/view/all/job/DDOC/job/publish/lastFailedBuild/console
