Prep work for generating Nomenclature and Getty class hierarchies

[baskaufs]

After meeting with Shenmeng on 2022-04-08, @baskaufs is going to look at using NetworkX to create a nx.Graph object using subject/object node values from SPARQL queries. See this page for a tutorial and this page for notes on how to generate the tree diagrams in an organized fashion.

@dannihuang830 is going to work on cleaning up the nouns column in the 3d_parts.csv spreadsheet so we can regenerate the thesaurus_ids.csv spreadsheet to use for generating the graphs.

Created test Colab notebook to generate hierarchical diagrams: https://colab.research.google.com/drive/1ayAiYmL77ZsqLU4DNkfDIr1P4y65HA9l?usp=sharing I couldn't get the PyGraphviz module to install locally, but it was already installed in the Colab environment.

Added cells to query_thesauri_for_descriptive_nouns.ipynb to generate and save the graph, which can be uploaded to the Colab notebook for visualization.

There's too many categories to put on one graph, though.

Shenmeng suggested on 2022-04-12 to position labels using https://stackoverflow.com/questions/49368341/position-showing-of-labels-with-networkx-graphviz

Just saw a demo of a great Wikidata tool for exploring trees: https://www.entitree.com/ . For example https://www.entitree.com/en/subclass_of/Q4502142?0d0=d
