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

El issue no indica ningún archivo de implementación ni ninguna prueba. Empieza por localizar el punto de entrada del treemap y las pruebas existentes de layout o rendering; después, compara cajas anidadas con y sin el espacio de la etiqueta. La tarea debería proporcionar una forma de eliminar ese espacio para que las áreas hijas sean más grandes y las proporciones sigan siendo visualmente comparables.
