`ontology_viz.py` hangs #14

Calling ontology_viz.py it is not responding with output. If I Ctrl+C abort the process, I get the following error:

Traceback (most recent call last):
  File "/home/ch/repos2/ontology-visualization/ontology_viz.py", line 23, in <module>

KeyboardInterrupt

However, the fork https://github.com/fatestigma/ontology-visualization works (and immediately responds). Tested on Ubuntu 20.04, with Python 3.8.10, and python3-rdflib 4.2.2-5.
