@arcy well yeah, you can draw things and change them on the spot, as well as change them dynamically (based on knob value, counter for animations etc.)
You could argue that the advantage to use SVG over local look and feel or paint routines is that it's easier to get shapes down but I would disagree, I find it easier to get things down progfamatocally with numbers and formulas than manually dragging elements around in figma or photoshop, especially if you define everything with constants, as that makes any changes super easy to make.
