python上的鱼骨图

Question

I was trying to create a Fishbone Diagram also known as cause and effect diagram or Ishikawa diagram on Python. Can anyone help me to make it more like standard fishbone diagram? im not really familiarized with the dot language, and the script i used was from a previous post in the forum

This is what i have done so far And this i what i want

       graph W {
      graph [splines=line]
      node [shape=underline]
      {
        rank=same
        node [shape=rect style=invis centerline=true]
        edge [headclip=false tailclip=false]
        p1 [group=g1]
        p2 [group=g2]
        p3 [group=g3]
        pstart:c -- p1:c --  p2:c --  p3:c
        pend [label=" Defect XXX" shape=plain style=solid]
        p3:c -- pend:w [dir=forward arrowhead=normal]
      }
      {
        rank=min
        node [shape=plain]    
        measurements  materials personnel
      }
      {
      node [group=g1]
      measurements:se -- calibration:e -- microscopes:e -- inspectors:e
      inspectors:e -- p1:c  [headclip=false]
      }
      {
      node [group=g2]
      materials:s--alloys:e--Lubricants:e--Suppliers:e 
      Suppliers:e -- p2:c [headclip=false]
      }
      {
      node [group=g3]
      personnel:s--shifts:e--training:e--operators:e--"another thing":e -- p3:c [headclip=false]
      }
      {
        rank=max
        node [shape=plaintext]
        Environment Methods Machines
      }
      {
      node [group=g1]
      p1 -- Humidity:e [tailclip=false]
      Humidity:e -- temperature:e -- Environment:n
      }
      {
      node [group=g2]
      p2 -- Angle:e  [tailclip=false]
      Angle:e --Engager:e-- Brake:e-- Methods:n 
      }
      {
      node [group=g3]
      p3 -- "blade wear":e  [tailclip=false]
      "blade wear":e -- speed:e -- Machines:n
      }
    }
   

 BEGIN{int nIndx=0;
  float centerY=-999.9, dY, angleAdj, minY=9999, maxY=-9999;
  node_t Node[];
  graph_t theRoot, subG;
  void doErrs(string eString){
     printf(2, "Error:: %s\n", eString);
     print("// Error:: %s\n", eString); // temporary, for debugging
  }
}

   Node[++nIndx]=$;
   if ((hasAttr($, "centerline")) && ($.centerline!="")){
      centerY=$.Y;
   }
   if ($.Y >maxY)
     maxY=$.Y;
   if ($.Y < minY)
     minY=$.Y;
}

    END_G{
      if (centerY==-999.9){
          estr="\"centerline\" attribute is missing"; doErrs(estr);;
          exit(9);
      }
      $G.bb="";
      for (Node[nIndx]){
        print("//  pos before: ",Node[nIndx].pos);
        dY=Node[nIndx].Y-centerY;
        print("//  dY (1) : ", dY);
    
        if (dY<0){
          dY=-dY;
        }
        print("//  dY (2) : ", dY);
        Node[nIndx].pos=(string)(Node[nIndx].X - .25*dY) + "," + (string)Node[nIndx].Y;
        print("//  pos after: ", Node[nIndx].pos);
      }
    }
