 ### What is orca?
 Orca is an [Electron](https://electronjs.org/) application that inputs plotly figure specifications and converts them into static images.  Orca can run as a command-line utility or as a long-running server process. In order to provide the fastest possible image export experience, plotly.py launches orca in server mode, and communicates with it over a local port.
