Uses PyGraphviz to visualize a Weaviate schema (ontology)
Paste your ontology schemas in the folders weaviate_data: things and actions, with the filenames schema.json in each folder.
Note: only test it with Python3
Generate visualization:
$ python viz_schemas.py | dot -Tpdf > schema.pdf
For Windows systems:
$ python viz_schemas.py > viz_code.txt
The code generated and written to viz_code.txt can be copied to https://dreampuf.github.io/GraphvizOnline/ to view the graph.
