Well, there was at least one, that seemed possibly relevant to you.
I’m not exactly sure what’s possible with (Pluto and its associated) extra packages.
But I was starting watching this seemingly awesome YouTube video, and see what’s possible in JavaScript (you need to see at that timestamp, video is better than words):
I was not a fan of JavaScript the language, but I want this in Julia! I was going to post a new thread on Discourse, asking if this is already possible, and I saw your post. Maybe it it. I recall similar in Pluto (e.g. sliders, but I seem to recall more setup was needed).
I didn’t mean to highjack your thread in case this isn’t somewhat related to your question. Then I move it.
What do you mean old? The first version is from 31 Oct 2021, so I do not consider this an old project already (I was even going to say Pluto is the new thing, but I see the first version is from 9 Mar 2020 so a judgement call).
