Treemap improvement

[IpadDilectio]

Hello
I am a philosophy teacher and I use treemap diagrams to represent Porphyry's trees. I would need several improvements:

• Ability to enter text that wraps to the next line
• Ability to change the size of each piece of text.
• The ability to use markdown (bold, italics) to emphasize text.
• It's difficult to know if this is possible given the principle of treemaps, but I would sometimes like to change the order of the cells and be able to choose to place them horizontally rather than vertically, and vice versa.

Thank you for allowing us to create treemaps with Mermaid!
I know that I am diverting treemaps from their original purpose, but they are very useful for easily creating Porphyry's trees and making them easy to remember.
An example of Porphyry's trees to define the concept of freedom of quality (in French):

If I could make the text wrap to the next line, the cells could be larger and the text would therefore be more visible.

Best regards
