Question: should I use `%matplotlib widget` or `%matplotlib ipympl`

Personne n'a encore pris cette issue.

the README suggests to use
`%matplotlib widget`

however based on a small experiment that I described also here
https://discourse.jupyter.org/t/interactive-matplotlib-in-jupyterlab-no-longer-working/20017/3?u=parmentelat

it seems like using
`%matplotlib ipympl`

works too, and even better in the sense that it works also in vs-code
so, which is best ?

(I have several hundreds of notebooks written with
`%matplotlib notebook`
and that now must be changed for jlab4/nb7 at least, so as far as possible Id like to change them only once ;-)

and thank you for the awesome tool 👍

Commencez par les indications du README concernant `%matplotlib widget` et comparez-les au comportement signalé de `%matplotlib ipympl` dans JupyterLab et VS Code. Examinez l’expérience Discourse liée et déterminez quelle recommandation la documentation devrait donner pour les notebooks existants utilisant `%matplotlib notebook`. C’est terminé lorsque le README indique clairement quel backend utiliser et où il fonctionne.
