 The module provides various sinks and widgets to allow interaction with the live GNU Radio applications remotely over the network. The module uses [Bokeh](https://bokeh.pydata.org/en/latest/)'s client API and streaming features. Using widgets and plots from Bokeh, the module enables the GUI for GNU Radio that renders in web browser. Just like `gr-qtgui`, it is fully integrated with GRC to allow easy use.
 
 The module was developed as a part of Google Summer of Code 2017.
