How to draw a parse tree using jsSyntaxTree

I've got this code that I need to draw a parse tree:

for(id=num;id<=num;id=id+1){ 
   id=id/num; 
   if(id==num){ 
      id=id*num; 
   } 
   else{ 
      id=id+num; 
   } 
}

I saw in other post someone suggesting to use this site: https://ironcreek.net/syntaxtree/. How can I use it?
