Builder tool has codegen in right-mouse button menu on top of a node.

When you have created a full graph, the last item should be run_window.

From run_window, you can do codegen that outputs the right piece of code,
assuming that all the left-side slots have been connected to other nodes.

The output from codegen looks like this:

P I1=ev.polygon_api.cube(-200,200,-200,200,-200,200);
LI I2=ev.lines_api.from_polygon(I1);
MT I3=ev.materials_api.m_def(ev);
MT I4=ev.materials_api.phong(ev,I3,-0.3,0.3,-1,ff008800,ff006600,50);
PT I5=ev.point_api.point(0.0,0.0,0.0);
MT I6=ev.materials_api.fur(ev,I4,I5,60.0,1.59,1500,2.0,4);
ML I7=ev.polygon_api.line_to_cone2(ev,I2,40,15,I6);
MN I8=ev.move_api.mn_empty();
MN I9=ev.move_api.rotate(I8,0,10000,0,0,0,0,1,0,628);
ML I10=ev.move_api.move_ml(ev,I7,I9,1,10.0);
RUN I11=ev.blocker_api.game_window2(ev,I10,false,false,0.0,100000.0);

This kind of output need to be copy-pasted and moved to the actual
html file.
