Description	A globally distributed multi-model database service on Microsoft Azure with property graph support through the Apache Gremlin API. Offers multi-region replication and multiple consistency models.	A loadable SQLite extension that adds property-graph storage and openCypher querying to any SQLite database, keeping graph and relational data together in a single zero-config file. It ships with 15+ built-in graph algorithms—PageRank, Louvain, Dijkstra, centralities—plus Python and Rust bindings, and inherits SQLite's embedded, serverless ACID operation.
