Perspective is an <i>interactive</i> visualization component for <i>large</i>, <i>real-time</i>
datasets. Originally developed for J.P. Morgan's trading business,  Perspective
makes it simple to build real-time & user configurable analytics entirely in the
browser, or in concert with Python and/or
[Jupyterlab](https://jupyterlab.readthedocs.io/en/stable/).
Use it to create reports, dashboards, notebooks and applications, with static
data or streaming updates via [Apache Arrow](https://arrow.apache.org/).

## Features

- A fast, memory efficient streaming query engine, written in C++ and compiled to [WebAssembly](https://webassembly.org/), with read/write/stream support for [Apache Arrow]().

- A framework-agnostic query configuration UI component, based on [Web Components](https://www.webcomponents.org/), and a WebWorker and/or WebSocket data engine host for stable interactivity at high frequency.

- A customizable HTML Data Grid plugin, and a Chart plugin built on [D3FC](https://d3fc.io/).

- Integration with [Jupyterlab](https://jupyterlab.readthedocs.io/en/stable/), both natively in a Python kernel, and as a notebook Widget.

- Cross-language streaming and/or virtualization to the browser via [Apache Arrow](https://arrow.apache.org/).

- Runtimes for the browser, Python, and Node.js.
