Find good visualisation ideas

(No coding involved, we will implement it later)
Sometimes it can be hard to display such information, particularly when you have multiple states to analyse. We need to find nice ways to visualise the polarization state(s) of a single photon, multiple photons, a large beam, a depolarized beam, etc.

Something like this could be nice to visualize propagation of a single vector.

I would also like a poincaré sphere showing the polarization state and how it evolved. Similar to this

We could also add interactivity and have a slider to view the polarization state at different point in the 'optical path'.

I found them easy to visualize polarization states on a sphere!
