Adding SVG element to an html file?

I'd like to a开发者_运维百科dd some SVG elements to an html file. I'm finding links which say this is not supported, the document type must be xhtml.

But I am using some javascript libraries with html that allow me to use SVG in them (Raphael, SVG Web, etc).

So is there a way to add a script to an html file which can dynamically add an SVG element to the document at run time?

Thanks

var svgnode = document.createElementNS('http://www.w3.org/2000/svg','svg');
var circle = document.createElementNS('http://www.w3.org/2000/svg','circle');
circle.setAttribute("cx", "100");
circle.setAttribute("cy", "100");
circle.setAttribute("r", "40");
circle.setAttribute("fill", "blue");

svgnode.appendChild(circle);
mydiv.appendChild(svgnode);

You might want to take a look at svgweb, which allows you to put SVG directly into a <script> tag in HTML. It will also emulate SVG support using Flash for browsers which do not have native SVG support.

edit: Hmm. I just noticed that you mentioned svgweb already. In what way does it not do what you want? You might want to clarify your question.
