Or embedding it directly into the HTML - almost any browser that can show SVG can also handle it as markup. But, the benefit of this technique (as far as I can tell) is decoupling, and any kind of embedding re-couples the data. Maybe in an acceptable way, if you can do it at a deploy step. It depends on what the use case is.
