SVG??

Nope. And I can see why. I could put JAVASCRIPT into my SVG, and your browser would be tempted to execute it!! SVG has to be sanitized as thoroughly as any query string you take in. This also explains why the one site where I am posting my SVG art does not let the events in them run. I can't build an animation that emits an end event to be used as a start event for the next animation. They all have to be time based.

<svg width="100" height="100">
  <circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
</svg>
