perspective

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.
