LevelGraph - Graph Database

LevelGraph is a graph database implemented for both Node.js and browser environments, leveraging the high-performance LevelDB key-value store through the `level` library. Currently stable at version 4.0.0, its release cadence appears to be tied to significant updates in its underlying `level` dependency, as seen with the v4.0.0 release updating to `level` v8. A key differentiator is its implementation of the Hexastore approach, employing six indices for each triple (subject, predicate, object) to ensure rapid data access and pattern matching. It supports standard graph database operations like triple insertion, retrieval, and deletion, with capabilities for advanced searches and filtering. It offers a consistent API across Node.js and browser contexts, though initialization differs slightly.
