Includes a virtual-scrolling, editable data grid, WebGL charting engine with 15+ chart types, tile-based geographic maps, full theme support, and React bindings. - A fast, memory-efficient streaming query engine written in C++ and compiled for WebAssembly (including a 64-bit memory64 build for in-browser datasets larger than 4GB), Python and Rust. Tables update incrementally and views tick in real time, with reactive joins across tables, a columnar expression language based on ExprTK, and read/write/streaming support for Apache Arrow, CSV and JSON. - A symmetric client/server architecture — the same Client API connects to an engine in-process, in a Web Worker, or remotely over WebSocket, with server bindings f…
