Nice post! And I love your question about why we don’t see more attention on data art. I’m a data artist myself at times, and usually show with organizations like Grayarea, here in San Francisco: https://grayarea.org/

Here’s an online version of the last installation I did with Grayarea: https://artatomic.itch.io/data-meditations-an-abstract-koi-pond

I’ve also seen some great installations at a tech art museum in Paris. I wish I could remember the name of it. I was in Paris for a data visualization conference and stumbled into the museum while out for a walk.
