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


The following metapost file duplicates your graph:

sx:=100; sy:=100;
draw z0--z1;
draw z0--z2;
draw z0--z3;

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

%%BoundingBox: -1 -101 101 101 
%%Creator: MetaPost
%%CreationDate: 2002.09.06:1231
%%Pages: 1
%%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

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