I have developed the library bertinjs which allows to make svg interative maps. In Observable, require("bertin") works. In Quarto, require("bertin") does not work. The following error is returned: OJS Error. RequireError$1: invalid module. See the issue on Github (see). It's weird. Any help is welcome.
(Quarto dev here) I recently fixed a bug that would cause that behavior you're seeing. Can you try a release later than 0.9.430? Thanks!
Edit: I see now that bertinjs uses modern JS syntax, which the stable versions of the RStudio IDE don't yet support. Your example works on the latest Electron daily builds, the right-most column on the linked page.
