iid= will never do id=

However

why not do:

onload="init(this)"

and:

function init(bigbox) {
   //var bigbox=document.getElementById("bigbox");

Methinks the mixture of ready svg and javascript induced shapes
makes the whole thing error-prone. I for one can't even deduce what you want 
to show.

Look at this nice and less error-prone full-javascript way:

<http://solvedstack.com/questions/javascript-createelement> 

Add just <!DOCTYPE HTML> to the top,
with that and var xmlns = "http://www.w3.org/2000/svg"
you don't seem to need the whole rigmarole.

You can inspect the resulting svg-code in the body
using F12 [in Chrome and other browsers]
