    V(svg)

Return a Vectorizer object. If `svg` parameter is a string, construct SVG DOM elements from the string markup. If `svg` is an SVG DOM element, just wrap that element by the Vectorizer object and return it. You can think of this function as of the jQuery $ function except that the `V` function does not accept selectors. The Vectorizer object contains a reference to the original SVG DOM element in its `node` property.

    var vel = V('<g><rect/><text/></g>');
    console.log(vel.node);
