Hi. Of course! If you have data classes, you can enable Analytics for your namespace, create a data cube, and then create various pivot tables in Analyzer. This will allow you to create visualizations.
 
Take a look at this docs

And this group of articles covers all the necessary features of analytics.

Hi @Jacinto Busquets !

I think your request is interesting, and I spent a vibecoding evening to introduce a sample that can help with the task.

So I've built a backend on IRIS that goes through persistent classes in a namespace and provides stats on the columns of every class how are they filled. And built a frontend for it. Here is the demo server:

How to have it on your own server: 

you should have IPM client installed, and then do:

USER> zpm "install iris-table-stats-frontend"

and

USER>zpm "install esh-iris-table-stats"

and open the UI at /iris-table-stats-ui/index.html endpoint of your IRIS server.
