Helpers to create dom svg graphic using javascript.
Ex. Create an html container
<div id="drawing">
than in js
//Svg element creation
//Please read about viewbox
var svg = svg("originale", undefined, "0 0 800 600" );
//Create a style
var rectStyle = new svgStyle(undefined, undefined, "lightgray" );
//Add rectangle
var rect = svgRect("rectangle", 0, 10, 100, 125, rectStyle);
svg.appendChild(rect);
//Svg container
var cont = document.getElementById('drawing');
cont.appendChild(svg);
Voilà.
