yes, \tree corresponds to [mathmode]insert->tree and works very fine for « vertical » trees

but 99% of probabitliy papers (at least in high schools) and 99% of screenshot on google image with keywords « probabillity trees »  have horizontal trees, not vertical one

i have no idea if it would be difficult for the developer team to implement it ; or maybe it is in project

also, Julien, you say « nested trees » 

do you mind nested trees exist in TeXmacs or do you suggest they would be welcome ?

In mode math, \tree works fine. Nested trees if you need more than a root and one generation of children.

One would need some kind of matrix transposition to make it horizontal.

How do you construct the vertical tree in TeXmacs? With the current TeXmacs, I would construct either tree with a drawing.

hello Giovanni

from TeXmacs (vertical) : <GraphiqueCollé-1.png>

preferred (horizontal) : <GraphiqueCollé-2.png>

when you type "tree probability » on internet you only get horizontal trees…
