Hi @mindaslab, thanks for the post!
And thanks for the important clarification, @p-himik, I believe you are right.
Indeed Clojupyter is not so active, at the moment.
Pink-Gorilla is very promising, but still work-in-progress. In addition to Clerk, another well-polished and friendly tool is Portal. The maintainers of these projects (and others) are extremely kind and helpful.
By the way, today we’ll have a community meeting with a few of the people creating visual tools around similar use cases. Maybe you’d like to join. A similar meeting took place a couple of months ago and may shed some light on the active projects in this field.
