How are these interactive visualizations made? As a senior machine learning engineer (with only rudimentary JS skills) it would be fantastically fun to make something like these.
Not sure what's the best starting point to learn, but there's lots of videos on YT to help you get started.
it provides you with an in-browser, graphical, node based interface where you can just connect boxes together and it will output js-code ready to implement in your website.
(disclosure: i know the dev plus am a huge fan!)
