Participants will learn how to use Perspective’s JupyterLab integration to first interactively develop, test and visualize a simple market model in a Jupyter Notebook; then, using that same model, we’ll develop a production-caliber, high-performance streaming server and interactive web client with Perspective and Apache Arrow.   ### **background for the finos perspective project** Perspective is an interactive visualization component for large, real-time 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/). As a library, Perspective provides both: - A fast, memory efficient streaming query engine, written in C++ and compiled for both [**WebAssembly**](https://webassembly.org/) and [**Python**](https://www.python.org/), with read/write/stream/virtual support for [**Apache Arrow**](https://arrow.apache.org/). - A framework-agnostic User Interface [**Custom Element**](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_custom_elements) and [**Jupyterlab**](https://jupyterlab.readthedocs.io/en/stable/) Widget, via WebWorker (WebAssembly) or virtually via WebSocket (Python/Node), and a suite of Datagrid and [**D3FC**](https://d3fc.io/) Chart plugins.

Morgan Chase** Andrew has been a web developer for 15 years. Despite winning the 2018 Nueske’s Bacon Night Award as a member of team “Lard and In Charge” at “Hogs for the Cause” BBQ festival, Andrew rejected a life of perennial BBQ fame and returned to programming full-time where he currently works on Perspective at JPMC.     **NEW: FINOS is rolling out a Community wide single sign on (LFID)  based on the** [**Linux Foundation LFX platform**](https://lfx.linuxfoundation.org/)**, so an LFID will be  required for this meetup. LF IDs can be created quickly and easily upon registration by authenticating with your Google, Facebook, GitHub, or LinkedIn account and allows managing all of your interactions and achievements across all Linux Foundation projects.** **After registration, you will be sent the Zoom link for the Meetup, as well as a calendar invite as a reminder.** **This session will be recorded. All normal** [**FINOS Community Code of Conduct**](https://www.finos.org/code-of-conduct) **applications apply to this Meetup.**   **[![REGISTER HERE](https://no-cache.hubspot.com/cta/default/2419532/0c87921e-5544-43da-9c5e-04fb3b6ae2c1.png)](https://cta-redirect.hubspot.com/cta/redirect/2419532/0c87921e-5544-43da-9c5e-04fb3b6ae2c1)And** *[![Sign Up for FINOS Updates](https://no-cache.hubspot.com/cta/default/2419532/8d9741ff-8809-4f66-848e-6ec47a7a11f2.png)](https://cta-redirect.hubspot.com/cta/redirect/2419532/8d9741ff-8809-4f66-848e-6ec47a7a11f2)*   ### Share this: - [Tweet](https://twitter.com/share) [![FINOS Logo](https://www.finos.org/hs-fs/hubfs/sofin%20assets/SOFIN%20LOGOS/FINOS_Icon_Wordmark_White.png?width=689&height=971&name=FINOS_Icon_Wordmark_White.png "FINOS Logo")](https://www.finos.org/) [![Twitter logo](https://finos.org/hubfs/2419532/FINOS/website/logos/social-logos/twitter-blue-social-panel.png)](https://twitter.com/finosfoundation) [![GitHub logo](https://finos.org/hubfs/2419532/FINOS/website/logos/social-logos/github-black-social-panel.png)](https://finos.github.io) [![LinkedIn logo](https://finos.org/hubfs/2419532/FINOS/website/logos/social-logos/linkedin-blue-social-panel.png)](https://www.linkedin.com/company/finosfoundation) [![SlideShare logo](https://finos.org/hubfs/2419532/FINOS/website/logos/social-logos/Homepage%20Social%20Panel/slideshare-logo.png)](https://www.slideshare.net/finosfoundation) [![YouTube logo](https://finos.org/hubfs/2419532/FINOS/website/logos/social-logos/Homepage%20Social%20Panel/youtube_logo-1.png)](https://www.youtube.com/channel/UCfJAdRALzJ7J7snubrb_Y-Q) [Contact Us](https://www.finos.org/contact-us) [info@finos.org](mailto:info@finos.org) +1 (650) 665-9773 [Privacy |](https://www.finos.org/privacy-policy)[Terms of Service |](https://www.finos.org/terms-of-service)[Community Code of Conduct |](https://www.finos.org/code-of-conduct)[Email Preferences](https://www.finos.org/hs/manage-preferences/unsubscribe-simple)
