@Orbifold something like this:

var el = $("<div>" + YOUR_HTML_CODE + "</div>").appendTo(document.body);
kendo.drawing.drawDOM(el).then(function(group){
    el.remove(); // remove the element from the DOM

    // group is an instance of drawing.Group
    // append it to whatever shapes you already have
});

Needed to hack it like this to make it work:

$.when(svgVisual).then(
                        function (root) {

                            if (root.hasOwnProperty("children")) {
                                root.drawingContainer = function () {
                                    return this;
                                };
                                root.redraw = function () {

                                };
                                that.shapeVisual = root;
                            }

                            else
                                that.shapeVisual = root;

                            that.visual.append(that.shapeVisual);
                            that.updateBounds();

                        }
                    );

the svgVisual is either an SVG element or a deferred kendo.dataviz.drawing.drawDOM(something). Internally the redraw and drawContainer methods are called, hence the dummies.

Very happy it works, just not very elegant, is it?
