perspective

Perspective is an interactive analytics and data visualization component, which is especially well-suited for large and/or streamingdatasets. Use it to create user-configurable reports, dashboards, notebooks and applications, then deploy stand-alone in the browser, or in concert with Python and/or Jupyterlab.

Features

• A fast, memory efficient streaming query engine, written in C++ and compiled for WebAssembly, Python and Rust, with read/write/streaming for Apache Arrow, and a high-performance columnar expression language based on ExprTK.

• A framework-agnostic User Interface packaged as a Custom Element, powered either in-browser via WebAssembly or virtually via WebSocket server (Python/Node).

• A JupyterLab widget and Python client library, for interactive data analysis in a notebook, as well as scalable production Voila applications.
