There is a rdf2dot tool in the rdflib library that might prove useful:

When it comes to manipulating and visualizing graphs in Python,
networkx is an option you need to consider:

   https://networkx.org/

On the Jupyter blog, you can also read about Cytoscape:

   https://cytoscape.org/

Looking at their "app store", I find
http://apps.cytoscape.org/search?q=semantic and
http://apps.cytoscape.org/apps/semscape

As you can see, there are many options.

I can not recommend one in particular, for I agree with Martin Hepp
that generic visualisation of RDF graphs is not that useful. Most of
the time you need to do a lot of filtering and pre-processing before
you can display something that provides readable information.

Hope this helps !
