I love it. I saw a comment in this thread saying that adding animation to a chart is pointless.

However in some public speeches, I've always wanted to add some cool charts to attract attention. Especially at large events, a slightly different presentation can make my stuff stand out and gain more attention.

Your work has a nice launch here in HackerNews but no upvotes on ProductHunt, so I just voted there to support you

Yeah, 100%. Just having something to move around catches the eye. Cheap trick but works - that's why most short videos have subtitles.

I love this idea. Problem is: it competes with "Hey Claude, take this diagram and animate it". The results are different (worse / better in different regards), but you can modify it more to your liking.

Maybe I'm not seeing the exact use case. I was very close to buying the plan (3 usd / m is a steal), but with Claude I can be more specific what I want.

Short videos have subtitles for engagement with those watching without sound (a significant proportion)

it depends, if I want to create and edit graph fast, make sure style is consistent etc. then this suits my needs better.

Yes. I could just render the .mmd plain as vanilla and will works just fine for devs but It may not get the attention of non technical folks

Motion definitely can help charts work better. Especially when the charts get really complex or detailed.
