Hi,

When I copy/paste ./ontology_viz.py -o test.dot test.ttl -O ontology.ttl in my terminal, I get:

[WARNING] Class http://dig.isi.edu/Time_Span doesn't exist in the ontology!
[WARNING] Property http://dig.isi.edu/at_some_time_within_date doesn't exist in the ontology!

When I copy/paste dot -Tpng -o test.png test.dot, I get:
dot: command not found

Any suggestions? Thanks!
