3B1B is incredible. I loved his video (https://www.youtube.com/watch?v=r6sGWTCMz2k) using Fourier series to make epicycle animations. I worked through the details to make my own: https://bldavies.com/blog/computing-epicycles/

Somewhat related/shameless self-plug: I created an R package [1] that provides data on travel times between NYC subway stops. These data can be used to, e.g., visualise and analyse the subway network [2].
