If you have a lot of "images" with such effects to generate from dynamic text, using SVG makes no sense, is vastly more complex and less flexible than the solution here.
You don't generate images, you just embed SVG nodes in the DOM. From the browser's perspective SVG and HTML elements are just two different types of element.
SVG is not great for text - HTML has more features - but for display text it's OK.
