Show and Tell - BeaconGraph


I wrote about it on my blog The general idea is to allow users to display wireless signal relationships (access point/clients). It uses Dash Cytoscape with a Neo4j database and displayed via PyQt5 widgets. In the blog post, you can see the improvement of trying to write the app myself to using Dash instead.

Thanks to the Dash team for all their hard work!


SO nice! Thanks so much for sharing :smiley_cat:


Thanks for the compliment.

One of the things I realized as I was setting this up with PyQt5 is that I could use callbacks as an extension to widget functionality for things I can’t exactly figure out in Dash.

For example, in this tool, I print the progress of parsing the input files to the console because I haven’t seen how to return that output to a Dash component repeatedly so that I can get a status popup at the top of the screen or something. I could probably output to a log file and use Interval to read it, but that seems clunky.

Instead, I can trigger the visibility of a PyQt5 widget using a callback and display console output in a small text box somewhere for roughly the same effect.

This can definitely lead to some interesting interaction between Dash and PyQt5.
