I usually make postscript files using metapost, then process
them with the utility mps2eps available at:

http://www.ida.liu.se/~joned/download/mps2eps/

The following metapost file duplicates your graph:

beginfig(-1);
sx:=100; sy:=100;
z0=(0,0);
z1=(sx,sy);
z2=(sx,0);
z3=(sx,-sy);
draw z0--z1;
draw z0--z2;
draw z0--z3;
endfig;
end;

Running metapost on this makes a ps file, and you
can load it in TeXmacs. It is short and sweet:

%!PS
%%BoundingBox: -1 -101 101 101 
%%Creator: MetaPost
%%CreationDate: 2002.09.06:1231
%%Pages: 1
%%EndProlog
%%Page: 1 1
 0 0.5 dtransform truncate idtransform setlinewidth pop [] 0 setdash
 1 setlinecap 1 setlinejoin 10 setmiterlimit
newpath 0 0 moveto
100 100 lineto stroke
newpath 0 0 moveto
100 0 lineto stroke
newpath 0 0 moveto
100 -100 lineto stroke
showpage
%%EOF

So mps2eps is not needed for this. However as soon as you 
start adding TeX labels to the document you want the 
utility mps2eps.
