Several of us have built visualization tools which produce output a bit similar to the one in this article for the aranet4 unit. These can be found linked from: https://observablehq.com/@thadk/aranet4-explorer.
Works best with the iPad app on an M1/M2 macOS computer.
There are also several other ways to get the output such as a bleak project on GitHub (https://github.com/Anrijs/Aranet4-Python).
