Perspective is an interactive analytics and data visualization component,

which is especially well-suited for large and/or streaming

datasets. 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](https://jupyterlab.readthedocs.io/en/stable/).

### Features

-   A fast, memory efficient streaming query engine, written in C++ and compiled

    for [WebAssembly](https://webassembly.org/),

    [Python](https://www.python.org/) and [Rust](https://www.rust-lang.org/),

    with read/write/streaming for [Apache Arrow](https://arrow.apache.org/), and

    a high-performance columnar expression language based on

    [ExprTK](https://github.com/ArashPartow/exprtk).

-   A framework-agnostic User Interface packaged as a

    [Custom Element](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_custom_elements),

    powered either in-browser via WebAssembly or virtually via WebSocket server

    (Python/Node).

-   A [JupyterLab](https://jupyter.org/) widget and Python client library, for

    interactive data analysis in a notebook, as well as _scalable_ production

    [Voila](https://github.com/voila-dashboards/voila) applications.
