Looks nice.

This terminal is not directly supported by draw, but you can use the 
'user_preamble' option to force output in svg format. Here is an example:

draw2d(explicit(exp(x)-1,x,-1,1),
              user_preamble=["set terminal svg","set out 'mysvg.svg'"]);

But you have to add by hand </svg> at the end of the file. For some 
reason this mark is sent to the console and not to the svg file, at 
least for me.

Maybe your gnuplot wasn't compiled with support for this terminal. It 
works for me.

No, sorry. But you can try something as this:

cl: makelist(random(10.0)+random(10.0)*%i,k,1,100)$
draw2d( point_type=diamant, points(map(realpart, cl), map(imagpart, cl)) )$
