Remove label gap in treemap

Hello. I have been finding plotly's treemaps very useful

One feature that I would find helpful is being able to remove the gap below each box label.

The problem is that for smaller boxes, the gap ends up taking a large amount of the space. This space is essentially wasted, and it makes each node's children proportionally smaller than they otherwise would be. This prevents an accurate visual comparison between one parent's children to another parent's children.

I have highlighted what I mean in the figure below using red arrows

Charts with lots of nesting would benefit a lot from being able to use this space

L’issue ne nomme aucun fichier d’implémentation ni aucun test. Commencez par localiser le point d’entrée du treemap et les tests de layout ou de rendering existants, puis comparez les boîtes imbriquées avec et sans l’espace réservé au label. Une fois terminé, il devrait être possible de supprimer cet espace afin que les zones enfants soient plus grandes et que les proportions restent visuellement comparables.
