Without seeing the source of your .svg, it's impossible to answer specifically...

<button id="trigger">Trigger Animation</button>

CSS

body {
  background-color: black;
  text-align: center;
}

svg {
  height: 100%;
  width: 200px;
  path {
    fill: white;
  }
}

JS

$( "#trigger" ).click(function() {
  document.getElementById("ani-circle").beginElement();
});

If you can't work it out from that, post the source of your .svg and I'll knock up a specific answer for you.
