Avoir une journée à peu près libre pour mettre à jour un cours ou deux, et apprendre de nouvelles techniques, c'est rafraîchissant.

Là : remplacer mes supports de cours PDF d'analyse spatiale sous R par des pages Quarto/Web-R interactives.

Observable Notebooks 2.0 Technology Preview.
I made some experiments with geoviz, geotoolbox, and the R data loaders.

See: neocarto.github.io/observable-n...

Conclusion
Notebooks 2.0 works perfectly!
You can now work offline.
Notebooks can be hosted and deployed wherever you want.
R data loaders allow you to chain together complex data import and handling operations at build time and document the process in a single notebook. This is great for traceability and reproducibility.
But

Syntax highlighting is missing for R cells.
An appropriate IDE would be needed to easily add chucks (cells). At this stage, Observable Desktop is only available on Mac OS.
Observable Notebooks 1.0 (on the web plateform) remain extremely important for sharing your work and building a community around data visualization.

pathLength makes makes SVG path animations easier to manage

Use the "pathLength` attribute to make animating "stroke-dasharray" and "stroke-dashoffset" easier.

The OSM dataset is huge, and keeps growing every day. Great news, of course, but sometimes the sheer volume can be overwhelming – there are just gobs and gobs of data! Hence, we created GOB (“Geo-Obj...

Yes, I did some tests here and here.

En géo, écrit par @fbahoken.bsky.social et @neocarto.bsky.social (et parce que j'avais utilisé une de leur séquence youtube ++ avec mes 4e en inspection ). Les vendeurs l'ont cherché 1 moment : "géopolitique ? Culture générale ? Il est difficile à classer"
