Wrap text in treemap

[DatsenkoIgor]

Hello, dear devs.
Please add possibility to wrap text in treemap.
95% of space is left empty, while all values are in the top string and they go waaaay over the border.
Thus it is impossible to work with several values in one rectangle.
Thank you.

Hi! wrapping text in SVGs is quite complex. Do you have any suggestion on how we could handle it?
