Bibliographic references from OpenAlex

This notebook downloads a small OpenAlex sample and loads it into both NetworkXGraph and Neo4jGraph.

Dataset notes:

papers from an OpenAlex search query
author nodes created from authorships
citation links are added when both papers are present in the sample
if network access is restricted, the loader falls back to bundled demo data
