How to add a link inside an svg circle

Question

I have drawn a circle using svg. This circle has a hover effect. I would like to add a link within in the circle and for the link text to change color along with the hover effect.

svg#circle {
  height: 250px;
  width: 250px;
}

circle {
  stroke-dasharray: 700;
  stroke-dashoffset: 700;
  stroke-linecap: butt;
  -webkit-transition: all 2s ease-out;
  -moz-transition: all 2s ease-out;
  -ms-transition: all 2s ease-out;
  -o-transition: all 2s ease-out;
  transition: all 2s ease-out;
}

circle:hover {
  fill: pink;
  stroke-dashoffset: 0;
  stroke-dasharray: 700;
  stroke-width: 10;
}

<svg id="circle">
        <circle cx="125" cy="125" r="100" stroke="darkblue" stroke-width="3"     fill="green" />
     </svg>

You need to add a text element wrapped in an anchor link.

Note, the text element, being on top of the circle will block the hover action on that circle. So, I've wrapped the whole thing in a g group and placed the hover capture on that instead.

svg#circle {
  height: 250px;
  width: 250px;
}
g circle {
  stroke-dasharray: 700;
  stroke-dashoffset: 700;
  stroke-linecap: butt;
  -webkit-transition: all 2s ease-out;
  -moz-transition: all 2s ease-out;
  -ms-transition: all 2s ease-out;
  -o-transition: all 2s ease-out;
  transition: all 2s ease-out;
}
g:hover circle {
  fill: pink;
  stroke-dashoffset: 0;
  stroke-dasharray: 700;
  stroke-width: 10;
}
text {
  fill: pink;
  font-size: 24px;
}
a:hover text {
  fill: blue;
}

<svg id="circle">
   <g>
  <circle cx="125" cy="125" r="100" stroke="darkblue" stroke-width="3" fill="green" />
  <a xlink:href="https://www.google.co.uk/" target="_top">
    <text x="50%" y="50%" style="text-anchor: middle">google</text>
  </a>
     </g>
