Perspective is an interactive visualization component for large, real-time datasets. Originally developed at J.P. Morgan, Perspective makes it simple to build user-configurable analytics entirely in the browser, or in concert with Python and/or JupyterLab. Use it to create reports, dashboards, notebooks and applications, with static data or streaming updates via Apache Arrow. As a library, Perspective provides both:

  • A fast, memory efficient streaming query engine, written in C++ and compiled for both WebAssembly and Python, with read/write/stream/virtual support for Apache Arrow.

  • A framework-agnostic User Interface Custom Element and Jupyterlab Widget, via WebWorker (WebAssembly) or virtually via WebSocket (Python/Node), and a suite of Datagrid and D3FC Chart plugins.
