DAGraph is a visual, graph-based data tool that runs entirely in your browser; no backend, no account. Nodes range from simple arithmetic up to OLAP SQL over Parquet, and the whole graph is reactive: change an input, downstream nodes recompute.
Built in Rust, targeting WASM (and native). SQL nodes use Apache DataFusion (Arrow + Parquet); UI is Egui; data is stored in OPFS using OpenDAL. Full bundle is under 25 MB (8 MB over the wire).
Built solo, still rough in places. Happy to get into the DataFusion/WASM side, the reactive graph, or any other technical details.
