Bon, pour le moment, dans les formats il n'y a que POVray,

mais Gnuplot et/ou Rdata arriveront bien un de ces jours.[source](exportbloubs.f90)

Un exemple : l'idée est de générer un fichier `.inc` pour
|
||||
Povray pour utiliser les données exportées dans une scène,
|

par exemple le barycentre des bloubs. Et c'est très facile
|

à faire avec un [script Awk](toinc.awk).

Nous avons des moyens assez simple d'enregistrer l'état complet

La meilleure preuve étant les vidéos publiés dans les peertubes.

comme la démographie, l'état de santé, la pyramide des ages...
