Add some more roadmapping...

This looks very interesting, but could use some description of what it is trying to do, and what it is trying to fix. I think it is
providing a draw-time interface to the data, including converting to array, and handling any unit conversion. I think it does this in a viewport cognizant way so that subsampling can also be handled by the wrapper? But I'm not clear on that from the examples.

All the examples should get a few more sentences, and a bit of explanation.

I appreciate that this is all proof-of-concept, not for user consumption, but I think writing some of these things down will really help clarify objectives at this point.

Commencez par examiner les exemples du dépôt et le comportement existant du conteneur de données afin d’identifier ce que le projet cherche à faire, en particulier l’interface au moment du dessin, la conversion des tableaux, la conversion des unités, la prise en compte du viewport et le sous-échantillonnage. Enrichissez chaque exemple de quelques phrases explicatives et documentez clairement les objectifs et le comportement afin que le proof of concept puisse être compris à partir des exemples.
