Dash DAQ

Dash is a web application framework that provides pure Python abstraction
around HTML, CSS, and JavaScript.

Dash DAQ comprises a robust set of controls that make it simpler to
integrate data acquisition and controls into your Dash applications.

The source is on GitHub at plotly/dash-daq.

These docs are using version 0.5.0.
