Data Commons (data-commons)

Data Commons is an open knowledge graph initiative led by Google that aggregates and harmonizes the world's public data into a single graph, making global statistical data simple to explore, query, and integrate through REST, Python, BigQuery, web component, and MCP interfaces.
