Just curious – any particular reason why did you choose to use long youtube videos [0] instead of rendering the visualization in-page (with D3 or something)?

[0] https://www.youtube.com/channel/UCnNlEbZNAN06j5IMKLJvkcg/vid...

And why is there not a slider so I can drag the time around and see how it looks later?

There is an input box above those videos, where you can specify the number from where do you want to watch. Example: https://prime-numbers.info/special/visual-type-comparison#pr...

Individual types have player with scrollbar- https://prime-numbers.info/article/semiprimes

My goal was first to create those videos. 3 months later I have decided to integrate them with website. Now I agree, that it looks cumbersome.

This is super confusing. Why is there color-coding if "color means nothing"? What is the vertical axis? Why are these pre-rendered youtube videos?

Thanks for feedback.

Dot travels from top left to the bottom right. Vertical axis shows which number is how far. It looked boring to me when I was using only single colour. I have more experience with using opencv for video rendering than JavaScript.

What would be good JavaScript library for this use case?

You could try Paper.js. If you use this, make sure to use Symbols instead of Path or Rectangle objects, otherwise you will run into performance issues quickly. There is an online editor at http://sketch.paperjs.org which is nice to play around with.

Thanks. I will take a look.

I have no idea what I'm looking at. I guess I wasn't sure what to expect going in, but I think it wasn't a couple of youtube videos and a grid.

What was your expectation? I wasn't able to came up with anything better. :/

If you have any suggestion how to visualize prime numbers differently, please, let me know. :)

I don't have any suggestions but I can say that this did nothing for me except leave me confused.

I wish there as a way to drag the horizontal to affect how the dots wrap around

How about changing numbers like on flip calendar/clock?

What does the vertical axis mean?
