README.md

Perspective is an interactive analytics and data visualization component for large and streaming datasets. Build user-configurable reports, dashboards, notebooks, and applications with a high-performance query engine compiled to WebAssembly, Python, and Rust.

Features

A framework-agnostic user interface packaged as a Custom Element, which connects to a Data Model in-browser (via WebAssembly) or remotely (via WebSocket, with integration in Python, Node.js and Rust). Includes a data grid, 10+ chart types line, bar, area, scatter, heatmap, treemap, sunburst, candlestick, and more.
A Data Model API for pluggable engines, enabling Perspective's UI to query external data sources like DuckDB while translating view configurations into native queries.
A fast, memory-efficient streaming Data Model built-in, written in C++ and compiled for WebAssembly, Python, and Rust. Supports read/write/streaming for Apache Arrow, with a columnar expression language based on ExprTK.
A JupyterLab widget and Python client library for interactive data analysis in notebooks.
