I did not know that TeXmacs has a "graph2d" command. The graphs look 
very nice, but does one need the next version of TeXmacs (or the SVN 
revision 12502) to be able to run the commands and get the output? The 
command in the first field

($strong "Hello")

works with TeXmacs 1.99 only after I use the stree->tree function

(stree->tree ($strong "Hello"))

and the graphics command gives me:

Unbound variable: $grid
