Perspective is an interactive analytics and data visualization component, which is especially well-suited for large and/or streaming datasets. Originally developed at J.P. Morgan and open-sourced through the Fintech Open Source Foundation (FINOS), 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.
