How do I configure Safari to show SVG locally?
===

I checked to see if there was something wrong with Safari in general when it comes to rendering SVG, but an SVG drawing on a website works just fine: http://phrogz.net/svg/svg_in_xhtml5.xhtml 

My conclusion was that there is something about Safari that keeps me from rendering SVG elements locally. This is the code that I have: 

    <!DOCTYPE html>
    <html lang="en">
        <head>
            <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
        </head>
        <body>
            <svg width="500" height="500" xmlns="http://www.w3.org/2000/svg">
                <circle r="50"></circle>
            </svg>
        </body>
    </html>

What can I do so that the above SVG circle renders on Safari? Is there something wrong with my code?
